Yes, even in Eternia there is Christmas, or an approximation as such. The whole cast of characters from both the He-Man & She-Ra toy lines found their way into this 45 minute toy commercial.
Orko gets transported to Earth during the test of a spy satellite. He makes it back to Eternia with 2 children in tow. Since it is Christmas on Earth, the kids are filled with holiday spirit that catches on in Eternia. Horde Prime & Skeletor don’t like it and will stop at nothing to quash it.
Apparently this is an “official” release on YouTube according to the user. Merry Christmas!
