Oh man, Twas the Night Before Christmas was one of my favorites when I was a kid. This was taped on the same cassette as Christmas Toy, so it got quite a fair share of replay growing up. The mice family that was a mirror of the clockmaker family? So great.
Even more so when you realize it’s Gomez Addams doing the voice of the father mouse. EDIT: D’oh, I’m wrong, it’s a totally different actor. Childhood=ruined.
The best character is Albert, the nerdy Santa skeptic who puts his entire town on Santa’s naughty list. Apparently all it takes is one nasty letter to the Kringle before he scratches your city off his flight plan, regardless of species.
Remember kids, never teach mice to write.
