By the horns of everything satanic.

I know its a Christmas movie but I just had to share. Watch for the part where lil' Lupita sees two creepy hand puppets have rough man-puppet sex. If you can sit thru that there is a section later on where Lupita dreams of two-faced dancing zombies that emerge from flip top coffins.
The zombies show Lupita their knickers.
