Bikini Bottom 500 is a SpongeBob SquarePants Plug It In & Play! motion racing video game. The controller is motion sensitive, allowing the players to control their boat mobile.
For each course (track), the player will compete against five computer players (Patrick, Squidward, Sandy, Mr. Krabs, and Plankton) to win a trophy by finishing first, second, or third to make three laps around the course. The player must also dodge obstacles such as jellyfish and rocks, as well as ones laid by the competitors (see below). When the player runs into an obstacle, his/her boat mobile receives some damage. If the boat mobile receives too much damage, he/she will forfeit the race. There are also UltiMotion minigames in each course, requiring players to do what the activity on-screen says to do. Another minigame is optional for adding health to the boat mobile, similar to the UltiMotion events.
