Jack is a three-year-old chimpanzee who has been the subject of a long-term experiment by Dr. Kendall, a researcher who been teaching Jack to communicate through sign language. Jack scrambles onto the ice in the midst of practice for Steven's junior league hockey team, and he and his teammates discover the monkey has a natural talent for the game.

MVP 2 opens with the lovable Jack being ousted from his hockey team, the Seattle Simians, and having to hit the road after being falsely accused of league misconduct. Jack ends up in the city, where he's befriended by Ben, a homeless skateboarder, and Ollie, a skate shop owner. Jack proves to be as adept at mastering the half-pipe as he does at delivering a slap shot, and before long, he and Ben are crashing amateur skateboarder competitions all over the country.

The athletically inclined chimpanzee Jack takes to the slopes. After meeting with some children in Colorado, the charming creature soon tears up the mountainside on a snowboard.
