Father Christmas.

Michael never believed in Father Christmas. He took great pleasure in telling children that he did not exist and that their parents were the ones putting presents under the tree. He was truly a modern-day Grinch.

When Father Christmas heard about this, he wanted to teach Michael the true meaning of Christmas. So he transformed him into a beautiful woman, dressed him in a Santa suit, and sent him out to deliver presents while embodying the spirit of "Ho Ho Ho."
