Here, There, Skeletors Everywhere

Man-at-Arms creates a duplicating machine, but it doesn't work quite as well as he'd expected. It makes a copy of whatever is put under it, but the copy is smaller. Skeletor finds out about it and when Man-at-Arms leaves it for the night, intending to come back at a later time for adjustments, Skeletor steals it and makes an army of small Skeletors that he calls Skeletoids to help him take over the Royal Palace.
