He-Man and She-Ra: A Christmas Special.

In this special Christmas episode of the He-Man and She-Ra cartoons, their sidekick Orko accidentally gets beamed to Earth during a test of a new spy satellite. Orko manages to get back Planet Eternia, but brings along two Earth children, Alisha and Manuel, with him. Since it's Christmastime on Earth, the kids are naturally filled with the holiday spirit, but this overflowing goodwill attracts the unwelcome attention of the Horde Prime and Skeletor. Will the combined power of He-Man, She-Ra and the spirit of Christmas be enough to stop them?
