Issue twenty-two of the UK Masters of the Universe comic attempted to solve one of the great He-Man mysteries: Why did Snake Mountain differ between the toy playset and the cartoon?
The Secret Files of Scrollos claimed that the first Snake Mountain design (the cartoon one) did not offer enough protection, prompting Skeletor to build the one that resembled the toy playset. Below is an image of the two comic panels (which originally appeared on separate pages). The UK comic also addressed why there were two different versions of the Fright Zone. But that is another post for another time! :)
