"Woodland Critter Christmas" is a song sung in the Season Eight episode, of the same name, "Woodland Critter Christmas". It is sung by the Woodland Critters and used as a commercial bumper throughout the episode, after receiving a Satanist touch.
The Woodland Critters sing as they prepare for Christmas and the birth of their Savior. After meeting Stan Marsh, they ask him to perform several tasks in order to help prepare for the Savior's birth. However, Stan is eventually informed that the critters are Satanists and their "savior" is actually the Anti-Christ.
It's almost time when the time is here,
The time that's only once a year.
We can hardly wait, 'cause it's so near.
A Woodland Critter Christmas!
Commercial Bumper Version
What special time and special day,
It's Woodland Critter Christmas.
