Cody Harmon, King of Pets (Franklin School Friends, Bk. 5)

Cody Harmon doesn't love reading, math, spelling, or really any of the subjects that Miss Molina teaches in her third-grade class. But he lives on a farm and he loves animals - he even has nine pets - so when the school holds a pet-show fund-raiser, it should be his time to shine. There's a ten-dollar entrance fee per pet, though, and Cody can't pay it for all nine pets. He'd love to take his pig, but what about the others? In the end, Cody figures out a way to lend out his pets so that every person in the class (and every pet) gets to participate in the show.
