Pilot is the first episode of Oh That Grinch!
The Grinch moves back to his hometown of Whoville. He calls his father, who refuses to meet with him, because he has to go to the game. The Grinch then meets with Jim the Cougar-Giraffe, who he then goes to the game with. He then embarresses his father by recounting a diarrhea-laden story from the lakehouse.
