Hi- i'm Arnold - 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 really scary and we really swimming in trouble- you'd never guess who helped us make The Great Shark Escape!
