Sore Ike! Anpanman: Santa ni Natta Chibi wo Ookami-kun  

それいけ! アンパンマン サンタになったちびおおかみくん

During a full moonlit evening, the Little Wolf transforms into a spectral wolf and embarks on a rampage. The next morning, he is discovered lying in the snow and is rescued by Santa and his reindeer Rudolf. Rudolf takes flight with the lonely-looking Little Wolf perched on his back. Christmas Eve is upon us now, with festive preparations underway in town. The Little Wolf seems to be enjoying himself immensely as he assists Santa in delivering presents to all. In return for his help, Santa bestows upon him a marvelous gift.
