Chapter 4: Thingamajigee, Thingamajigee, What Could You Be?

The students were shouting while they hid under Mr. R.'s desk.
"Is there anyone brave enough to see what's inside of Cocoa's mouth behind all of those very sharp teeth? asked Serena.
"Not me," whimpered David.
"Someone has to do it to see if there really is an elevator inside of there," said Justin.
"I guess I will," said Hannah, "like, what's there to lose? It's cocoa's mouth or being totally vaporized," and she slowly started to crawl over towards Cocoa's cage.
"Don't do it! Don't do it!" screamed the rest of the students, "It's too dangerous!"
"Really guys," Hannah said, "she's only a totally little guinea-pig. I even saw people eating them when I went to South America."
"Gross!" yelled the other students
Hannah kept on crawling. When she got to Cocoa's cage she carefully stood up. Cocoa, who was sitting in her cage chewing on a carrot looked out from behind her bars as if nothing strange had happened.
"Can you open your little mouth please?" asked Hannah.
"Now you can't possibly think that I'm going to open my mouth for free?Do you? What do you think I am, some sort of mouse or something?"

"Oh totally no!" screamed Hannah, "What do you want this time Cocoa?"
"How about everything in Mr. R's wallet?" suggested Cocoa.

"We can't take the teacher's wallet, besides, how are we going to get it? yelled Justin to Hannah, "He's busy vaporizing the school!"
"Mr. R's wallet is not in his pocket, it's on his desk," said Cocoa, "Get it!"
"But that's stealing!" yelled Serena, "We can't do that!"
"It's a matter of life and death, I'm sure Mr. R. will understand," said David, "Besides, he's the one vaporizing the school!"

Greg ran over and grabbed Mr. R's wallet from his desk.
"I want to see what's in here before we give it over to Cocoa," said Greg, "I bet we can use his driver's license and his video rental card!" That morning there had been $57.23 in the wallet, but Mr. R. Had spent $34.69 on the chemicals that he was using to vaporize the school...How much was left in his wallet?
