In "Woodland Critter Christmas," what do a group of Satanic woodland animals trick Stan into doing for them?

The animals claim that every year a mountain lion kills their Savior before it's able to be born. After killing the mountain lion, Stan is horrified to discover that the woodland critters are Satanists, and that their Savior is the Anti-Christ.
