Based on the episode Swiper's Favorite Things, this storybook tells about Swiper having a sleepover at his Grandma's House. He packs his pajama trunk, his favorite puppy book, and his special funny bunny. Uh oh! Just as he is about to leave, a big wind gust comes in and blows everything away! Dora and Swiper journey to Crocodile Lake, through the Jumbled Trees, and race to Strawberry Hill to get Swiper's favorite things back. Children can help Dora and her friends by looking for clues with the "spotting scope" in each scene and using the viewer to see colorful images from the story right inside the telescope.
