Here is another animated Christmas TV special straight from my childhood. I could barely remember seeing it as a kid until I saw it on YouTube. Anyway, this special is about six "horribly ugly, rougish, rascally, tricky, and troublesome" trolls who snuck into Santa's village dressed like elves to stop Christmas from coming.
With the vocal talents of Roger Miller (Disney's Robin Hood and Nestor the Long-Eared Christmas Donkey) and Hans Conried (Disney's Peter Pan), the animation from Atkinson Film-Arts, known for the four "Raccoons" TV specials, is one of the reasons I love this holiday classic. So that is all I have to say.
