Fugu Fish or Don't Pee On The Floor, Use The Commodore is a viral video of an ugly-looking yellow fish in a tank singing a song that states, "Don't pee on the floor, use the commodore."

The game was based on a French animated cartoon called Space Goofs, which premiered in 1997. Stupid Invaders involved aliens and their attempts to return to space, labeled under the umbrella of adventure games.
During one point in the game, the player is able to interact with a fishbowl in a lab. Once clicked on, a small cut scene takes place involving the pufferfish in the fishbowl singing a song with the lyrics, "Don't pee on the floor, use the commodore."
