When James accidentally drops some magic crystals by the old peach tree, strange things start happening. The peach at the very tip of the tree starts growing, and growing, and growing . . . until it's as big as a house! When James crawls inside, he meets a houseful of oversized friends—Grasshopper, Centipede, Earthworm, and more. With a snip of the stem, the peach starts rolling away, and the adventure begins!
