Help childhood pals Mr. Krabs and Plankton to rescue the recipe for Krabby Patties before it gets lost in the trash dump! The left and right keys move the two, while the space bar makes Mr. Krabs grab Plankton and throw him through seaweed to grab power-ups. The Krabby Patty gives the player bonus points, the dead fish gives the player another life to continue, and the paper piece is a lost part of the Krabby Patty recipe. If Mr. Krabs gets trapped in the gray cement, the player loses a life. If all 3 of Plankton and Krabs' lives are gone, it's game over. If the player collects all pieces of the ripped up recipe, they win the game.
In the game, the secret code "TENTACLES" can be entered to give the player a powerup to use during gameplay. The code was not advertised online or on television, and it could only be found in the source code of the game.
Black platforms cannot be broken and light gray platforms will break when one stands on them.
