Super Mario Bros. 3 is a platforming video game developed and published by Nintendo for the Nintendo Entertainment System (NES). It was first released in Japan on October 23, 1988, and later in North America on February 12, 1990. The game centers on Mario who must rescue Princess Toadstool from Bowser and the Koopa Kids.
In several levels of the game, staring in level 3-3, Mario (or Luigi) will encounter the Boss Bass enemy, a giant Cheep Cheep that pursues Mario throughout the stage. If Boss Bass catches Mario, it will swallow him whole, resulting an instant death and causing the player to lose a life.
- The original Super Mario Bros. 3 was remade and adapted to the Super Nintendo Entertainment System in the game Super Mario All-Stars. The gameplay and overall design of the game is the same, but with updated graphics. Thus, Boss Bass also appears the Super Mario All-Stars version.
