Hi, I'm Arnold. I'm one of the kids in Ms. Frizzle's class. I knew we were in deep when Ms. Frizzle announced our unit on ocean life, and I was right. On our field trip, we ended up underwater and face-to-face with all kinds of sharks, from great whites to goblin sharks. Then, when things got scary and we were really swimming in trouble, you'd never guess who helped us make the GREAT SHARK ESCAPE!
