Ivy's point of view:

"Hey, Lame-o," Alice said. "Get out of there. The zoo isn't even open yet."
Kowalski turned around and saw her. She laid a plank of wood down and told Kowalski to 交叉, 十字架 it. He obeyed, then Alice led him to the entrance/exit. The device (that's what I call it) was laying on the ground.
"No, Kowalski!" Skipper cried. 
He got out of our 圈, 圈子 and almost stepped on the device. 
"Wait!" Private cried, at the same time Skipper almost stepped on it.
Skipper just looked at Private, and continued. Private tackled him, to prevent him from becoming human.
"What are 你 doing?" Skipper asked him.
"Saving you! What else?" Private said.
"Get off me!"
Private got off Skipper, but tripped. I watched them, and thought like: "This is the best entertainment ever!" But that all stopped, because Private fell into the device.
The device did the same thing to Private as it did to Kowalski. Skipper moaned at the sight. 
"Not another one!" he said. "I thought Kowalski was enough!"
The remaining four of us ran over to Private. Skipper started arguing with Johnson about the device.
"How many times have I told you! Dispose of enemy devices before 你 enter!"
"I didn't know what it did! It could have been useful!"
"Useful to our enemies!"
While they argued, Rico and I helped Private up. Once we had successfully done it, he thanked us. 
I looked into my brother's eyes. I could see no way he had changed.
"I think I'd better get out of here before Alice sees me," Private said. 
Rico nodded and hacked up a board. Private laid it down and walked over it. He was just past the 狐猴 habitat when Alice spotted him. 
"Hey, kid, we're your parents?" Alice asked Private.
Private whimpered.
"Probrobly the guy who was here earlier," Alice said. "Who cares, go."
She led him over to the entrance/exit and pushed him out.
