Big Bird and Snuffy imagine they're on a trip somewhere very different from Sesame Street. They picture themselves on an island in the middle of the ocean, but don't have much to do as they didn't imagine a pail and shovel. After their fantasy, the two enjoy the idea of visiting someplace new so much that they decide to take a real trip. Remembering what happened during their imagining, they begin to start planning ahead. (thetvdb.com)
