Season 21

It's Pluto's birthday party, but the orphans seem to be having all the fun. Their present is a wagon so Pluto can pull them; the "Pin the Tail on Pluto" game doesn't go quite right, and everything seems to prevent Pluto from having his birthday cake, but Mickey has planned ahead.

Pluto comes bounding outside to help Mickey get a Christmas tree. Chip 'n Dale see him and make fun of him, but the tree they take refuge in is the one Mickey chops down. They like the decorations, especially the candy canes and Mickey's bowl of mixed nuts. Pluto spots them and goes after them long before Mickey spots them.
