e left straight from the mall, hopping a bus out to The Gardens, which is clear across the city.

On the way, I tried to catch up on my homework. I had missed a lot of classes that day, so I borrowed

class notes from my friends. Rachel kept perfect notes. Tobias had terrible notes with all kinds of

little drawings in the margins. It took a while before I could figure out what they were. They were

buildings and people and cars, the way they looked from high up in the sky.

"I don't really need to go in," Tobias said as we pooled our limited cash to buy tickets. "I'm

happy with just my hawk morph. I don't want to be anything else."

"I think that's a mistake," Rachel said. "Our one real weapon is the power to morph. We should

acquire as many useful morphs as we can."

"What kind of animal morphs are going to be able to deal with Visser Three when he turns into

that big monster that ate the Andalite?" I asked. There was nothing in this zoo or any other that was

going to kick that big monster's butt.

Marco winked. "Fleas? No one can kill fleas. We'll itch him to death."

I had to smile. "So now you're suddenly Mr. Hopeful?"

"No, I'm just so scared I'm getting weird," he said. "I haven't done this morphing stuff. You guys

all have. I'm not even a full-fledged Animorph yet I'm still normal."

"I still feel normal," Cassie said. She looked troubled.

"Cassie, you can turn into a horse," Marco said. "Very few normal kids can do that. It's different

for Jake, turning into a lizard. He's always been a reptile."

I took a good-natured swing at Marco, but he dodged it. It was cool having Marco with us - even

if he was giddy.

It took about a half an hour to reach the main gate of The Gardens. I climbed down off the bus

feeling nervous - not at all like I usually felt going there. I mean, The Gardens is just about my

favorite place to go, normally. But normally I'm not going there to get personal with dangerous

animals.

The main part of The Gardens is rides. They have all the usual stuff, like roller coasters, which

are my personal favorite, and Ferris wheels and water slides.

But they also have an animal part, which is like a zoo, only cooler. They do dolphin shows, and

there's this whole section where you can get close to some of the safer animals. And this monkey

habitat they have is like a whole monkey city, practically. Anyway, if I were an animal, and I had to

be in a zoo, I'd want to be there.

Cassie led us to the main building, which holds all kinds of exhibits. It has everything but the

really big animals that need lots of space. Those animals are farther out, mostly, in big grassy habitats

that look like parks. Parks with walls and moats and fences around them.

The main building is supposed to be like a rain forest, I guess. It's where they keep animals that

need to be warm all the time. There's a pathway that winds around with tall tropical trees overhead,

with bushes here and there between the exhibits.

Some of the exhibits are tiny, and some are really big, like the area they have for otters. It has a

waterfall and a water slide for the otters to play in.

We were near the otter habitat when Cassie stopped. "Okay, now everyone stay together, and try

not to be too suspicious-looking," she said. I'm taking you inside."

"Inside where?" Marco asked."Well, the way it works is, there are walkways behind all these exhibits. That's how they feed

the animals and give them meds or whatever. Meds are medicines. Sorry." She pointed to an

inconspicuous doorway. "Anyway, we can go in through there."

It was an odd change from outside to inside. One minute, we were in this fake rain forest. The

next minute, we were in what looked like a hallway at school. Only the smell was worse - kind of

damp and moldy and musty. More like the boys' locker room.

"Okay, look, if any staff people stop us, the story is we're here to see my mom," Cassie said. "Of

course, it's so late in the afternoon she won't be here. I hope. Because if she finds out I've been

dragging four of my friends around back here... Well, I can't be saving the world from alien invaders

if I'm grounded. Hopefully, there won't be many staff people here at all."

We shuffled along the hallway, feeling like we definitely did not belong. Which we didn't. On

either side of the main hall, there were side paths that led to the different exhibits. Unfortunately, the

doorways to the exhibits just had numbers on them. I knew we'd have to rely on Cassie's knowledge

to find our way around. Behind some of those doors were animals you didn't want to just walk in on.

"How do you guys feel about gorillas?" Cassie said. She had stopped by one of the numbered

doors. "This is Big Jim's cage. He just came over from another zoo, so he's in his own private

environment for now. He's very gentle."

Slowly it dawned on me what Cassie was saying. "Oh. You mean, does one of us want to acquire

his DNA?"

"That is why we're here, Jake," Rachel pointed out. She batted her eyes at Marco. "How about

you, Marco? Haven't you always wanted to be a big, hairy guy?"

Marco didn't look like he was crazy about the idea. But I knew how to handle Marco.

"Maybe Marco should try something easier for his first morph," I said. "You know, like a cuddly

little koala or something."

That did it.

"Koala?" Marco said, giving me a dirty look. "Open that door, Cassie." He hesitated. "You said

gentle, right?"

"Gorillas are extremely gentle," Cassie said. Then, in a quieter voice, she added, "Unless you

make them mad."

Cassie opened her backpack. She took out an apple and handed it to Marco. "Here. You just

open the door. The way it's set up, none of the visitors will be able to see you unless you walk clear

out into the cage. Besides, there's an extra security gate, so he can't just jump out and you can't just

walk in. So we just open the door, and hope Big Jim feels like eating."

Behind the door was a second door of steel bars, with a little cutaway section for the handlers to

shove the food through. The entire door opening was concealed behind a fake rock ledge so it wasn't

visible to the people looking into the cage. But Big Jim noticed us right away. He climbed heavily

down from his perch on a rock ledge and took a good look at us through the bars.

Big Jim was definitely big. He had fingers the size of my wrist. But Jim didn't seem to mind us

being there. Mostly he seemed interested in Marco's apple. He looked Marco over, snorted like he

wasn't impressed, and then held out his hand.

"Hand him the apple," Cassie directed. "He wants the apple."

"I loved your work in King Kong Versus Godzilla" Marco told the ape. He stuck his hand

through the bars and held out the apple. With surprising daintiness, the gorilla lifted the apple and

began inspecting it closely.

"Hold his hand," I said. ""Yeah, right," Marco laughed.

"When you acquire DNA, the animal goes-into a kind of trance," I said. "Go ahead, grab his hand

and concentrate."

Marco tentatively touched the gorilla's wrist. "Nice monkey." The gorilla ignored him. Big Jim

was much more interested in the apple than in any of us.

"Concentrate," Rachel urged.

Marco closed his eyes. The ape closed his eyes.

"This is so cool," Tobias commented. "You realize that gorilla could pull Marco apart like he

was a paper doll. Look at those arms!"

Marco opened one eye. "Tobias? Being terrified gets in the way of concentrating. So how about

if you shut up about his arms?"

Suddenly I heard a whirring sound. I looked down the hall, then back. It was one of those

electric carts, like a golf cart. It was coming toward us.

"Just act natural," Cassie hissed. Marco slipped out and she slammed the door on Big Jim. "As

long as it isn't a security guy, we're probably okay."

The cart came up to us. Its driver was a man wearing a stained, tan lab coat over his jeans. In the

back of the cart were two large white plastic buckets full of something brown and horrible-smelling.

"Hey, you're Cassie, right? The doc's kid? How's it going?"

"Fine," Cassie said. She waved casually, and the man drove right on past.

"That was easy," Rachel said. "He didn't even seem to care that we're back here."

"Well, where next?" Cassie wondered. We were at a four-way corner. There were blank, whitepainted hallways in all directions. An electric golf cart was parked there, too.

"What are we near?" I asked.

Cassie thought for a moment. "Okay, that walkway leads to the outer exhibits. That one leads to

the offices and storage facilities. These two go around the main building exhibits. We're close to...

let me see... um, bats and snakes that way. The jaguar and the dolphin tank that way."

Rachel started down the hallway to our right. "Dolphins. I love dolphins."

"Wait," Cassie said, trotting after her. "What are we going to do with dolphin morphs?"

"I think we should go out to the big exhibits," Marco said. "Let's get serious about this. We need

firepower. Come on."

"Let's stick together," I said as Marco started down the hall. I reached out to grab him before he

got too far away.

And that's when the voice yelled, "Hey! Hey, you! What are you kids doing back here?" I saw a

guy in a brown uniform.

"Security!" Cassie yelped. "Oh, man, they'll take us all in to the office. They'll call my mom. I do

not want to explain this to her."

"Split up!" I said, trying to sound like a leader. "Just like at the construction site: One guy can't

get us all!"

"This guy looks like my grandfather," Rachel said. "Not like that Hork-Bajir that was after us."

"You kids hold on!"

"Oh, man. Oh, man," Cassie said. With that, she took off down one hallway. Rachel and Tobias

went after her.

Marco was already twenty yards down the other hall, the one that led out to the large exhibits. I

ran to catch up.

The guard reached the corner. I saw him glance toward Tobias and the girls. Then he looked atme and Marco. I guess Marco and I looked more suspicious, because he chose us.

"Stop! You kids better stop!"

"Let's grab the golf cart!" Marco said.

"Steal a golf cart?"

"If we don't take it, that guard will."

"Good point."

We jumped in the cart. Marco slid behind the wheel. He turned the key to "on." He looked at me.

"Just like driving bumper cars, right?"

"Only you try not to hit anything."

He put his foot down on the pedal. The electric motor made a whirring sound, and we took off.

Straight toward the wall.

Bam!

"Hey, try steering," I yelled.

We backed up and took off again. We picked up speed. Enough to pull away from the guard, but

when I looked back, he was still jogging after us.

"He's going to have a heart attack," I said.

"Which way?"

"What?"

"Which way?"

I turned around to face forward. We had reached a "T" corner. "Right!" I yelled.

Naturally, Marco turned left. I nearly fell out.

Almost immediately, we reached another corner. This time Marco did choose right. And I did

fall out of the cart.

I hit the linoleum and rolled. Then I was up and racing to catch the cart.

"What are you doing?" Marco demanded when he saw me. "Quit playing around."

I just gave him a dirty look and climbed back in.

"I think we lost the guard," Marco said.

"I'm fine, thanks for asking," I said. "Just a few bruises. Maybe a cracked skull. Nothing

serious."

"Where do you think we are?"

"I think we are in the longest tunnel I've ever seen," I said. It was more and more like a tunnel

now. The floor was still linoleum and the walls were still whitewashed, but the lights were getting

more spread out, so you definitely had the feeling you were underground.

"I wonder if they caught the others," Marco said. "Now do you see why it's crazy to think we can

beat the Yeerks? I mean, come on: We can barely beat zoo security."

"We haven't beat anyone yet," I said grimly. "Look!"

Way up ahead, there were two guys in brown uniforms.

"Maybe they don't know who we are," Marco suggested. "They might think we're regular

employees."

"Maybe. But not if they get a good look at us." I pointed. "There's a turnoff. Take it."

We turned. At the same time, the guards started yelling. The side corridor grew narrow. Too

narrow for the golf cart.

"Ditch it!"

I jumped out. Marco jumped after me. We could hear the guards' footsteps as they ran down the

main tunnel. These guys were in better shape than the old man. These guys could run.The corridor ended abruptly. There were two doors, one a little to the left, one a little farther to

the right. They were labeled P-201 and P-203. No help at all.

"Pick a door," Marco said.

I took a deep breath, "Door number one." I opened P-201. A blast of fresh air hit me. Sunlight

blinded me. I blinked, trying to get my eyes to adjust.

The rhinoceros blinked, too.

"Ahhhh!" I yelled.

"Ahhhh!" Marco yelled.

We jumped back and slammed the door.

"Wrong door!" Marco said.

"Definitely wrong!" I agreed.

"Hey, you kids! Stop right there!"

The guards were just at the end of the corridor.

"Gotta try door number two!" I said.

"Do it!"

We opened the door and ran through.

There were trees all around us. Trees and grass. We were in the shade. Sunlight filtered down

through the leaves. Just ahead the bushes gave way to open grass.

"Where are we?" Marco asked.

"Like I know?"

We worked our way through some bushes, keeping a careful eye out in all directions. We didn't

see any animals. Just some birds up in the trees.

"Hey, there are people!" Marco said. He dropped down behind a bush and pointed.

There were people lined up behind a railing. They were high up. Or else we were low down. I

parted the bushes to get a better look. The people were leaning against a railing at the top of a high

concrete wall. They couldn't see us because of the bushes. But they were definitely all staring at

something.

"We're definitely in one of the habitats," I said. "Those are people looking at... at whatever is

in here with us. I'm just hoping it isn't that rhino. That thing was way too big."

"How do we get out of here?"

"I don't know, let's just get away from the door. Those guards will be coming after us any

second." But, you know, in the back of my mind I was thinking, Hmm, why haven't those guards come

after us yet?

Marco and I crawled through the bushes and around the bases of the big trees. We reached a

corner of the wall, hidden from all the people above.

"That is an awfully high wall," Marco observed. "That's got to be thirty feet high. This is not

good. That wall is high for a reason. There's something in here that they don't want to escape."

I scanned the wall. There was a steel ladder set into the concrete about fifty yards away. "I guess

that's the only way out."

"Let me ask you something," Marco said. "Why haven't the guards come after us? I mean, if this

was, like, the deer and antelope exhibit, they'd come right in, wouldn't they?"

"We have to think, not panic," I said. "I am trying not to think about why the guards didn't come

in here." I moved back into the shadows of the bushes. "Besides, maybe there's nothing in here at all."

I squatted down on my haunches.

My butt touched something warm.I had a terrible feeling right at that moment. I looked up and saw Marco. Normally, Marco has

kind of a dark, tanned face. But his face was white. And his eyes were very large.

"Marco," I said, very slowly and very quietly, "is there something behind me?"

He nodded.

"What is it, Marco?"

"Um... Jake? It's a tiger.
