Muck The Elf Bob the Builder : Season 20 Episode 16

While erecting a Gingerbread House display at the plaza, Muck obsessively takes on the role of a Christmas elf – zipping around helping make the season special. He tries building a toy go-kart, decorating a Christmas tree, and even delivering presents. Unfortunately, his efforts don’t seem to be as helpful as he intended. Muck realizes that he is most useful when he helps with things that he is good at doing and assists Bob by collecting supplies for the display. Meanwhile, Wendy and Bob exchange hand-made Christmas cards.
