Continuity mistake: When the buses are loading at the market parking lot, the Chevrolet and GMC buses in the lot turn into Fords and Dodges when they arrive at Camp Northstar.
Audio problem: At the beginning of the hot dog eating contest Morty is stating all the rules but his mouth isn't moving.
Continuity mistake: At the dance when Bill Murray is dancing Crocket is behind him dancing with Wendy. When the shot flips Crocket is talking to Wheels. When it flips back to Bill Murray Crocket is dancing with Wendy again.
Deliberate mistake: In the basketball scene against Camp Mowhawk, the Mowhawk players' shorts have been pulled down a little, making it easier for the Camp Northstar players to pull them down all the way.
Continuity mistake: The score of the basketball game between North Star and the Mohawks is the same at the beginning of the game as it is before the start of the second half. The score reads 34-12.
Suggested correction: Actually the numbers represent the periods of the game.
Continuity mistake: When Bill Murray is running from the basketball game to get on the bus he's wearing a sport jacket - a second later when he gets on the bus he's wearing just a T-shirt.
Suggested correction: The jacket is right next to Bill on his left side.
