Fly Guy: #4 There Was an Old Lady Who Swallowed a Fly Guy by Tedd Arnold
When Buzz visits Grandma, Fly Guy goes along for the ride. Oops! Grandma swallows Gly Guy, then a spider, a bird, a cat, a dog, a goat, and a cow. She's about to swallow a horse when Fly Guy shouts: BUZZZ! Fly guy escapes and all the critters follow. And everyone lives happily ever after, of course!
