Surf's Up is a surfing game based on the computer-animated film of the same name. The Game Boy Advance port of the game features 5 players, with 2 available from the start, 5 areas with 1-3 stages each, and modes Championship and Minigames.
The Championship mode offers three options: Race, Freestyle, and Challenge. In Race mode, you compete against 3 CPU players to finish in one of the first 3 positions. Winning races unlocks more stages, areas, minigames, and characters. In Freestyle mode, your goal is to score a certain number of points before reaching the finish line, with new boards unlocking as you progress. The Challenge mode requires you to complete specific tasks, such as beating another surfer or gathering stars, to unlock rewards.
