Here we see Moss Man being decorated as a Christmas Tree by Orko and Stratos - never bet against He-Man!
Moss Man isn't just furry and green - the original version also smelled like an explosion at a rear-view-mirror-air-freshener factory, which makes him the perfect stand-in Christmas tree. There are no firs on Eternia.
The original version of this strip was Poe's Christmas card this year: we just decided to share it with everyone. The title is a line from the classic carol "O Tannenbaum."
