Dad assembles it, during the night's cold darkness, just before Christmas. Buster is intrigued by the large contraption, unaware of its use until a family of foxes, a skunk, squirrel and a hedgehog emerge from the shadows and put the trampoline to good use. While they have a blast, Buster watches from inside, jealous and angry.
On Christmas morning, the girl bounces out of her bed and outside to see her gift. Just as she's about to climb inside and bounce till her heart's content, Buster cuts her off, leaps in and has himself a merry little Christmas. As Buster jumps, the girl and her parents can only stare, with mouths agape.
