Baby Piggy and the Giant Bubble is a Muppet Babies storybook. Baby Piggy pretends she's inside a giant bubble, flying around outside. She imagines floating up to a tree and seeing a bird's nest with blue eggs, into a circus tent, past a soccer game, over the zoo, and high into the air. As she floats back down to the Nursery window, the other babies blow more bubbles for her to climb down after a bee pops her bubble.
