If the player goes to [[World 3-3 (Super Mario Bros. 3)|World 3-3]] or [[World 3-8 (Super Mario Bros. 3)|3-8]] and lets Boss Bass jump out of the water after Mario or Luigi, the player must repeatedly press {{button|gba|start}} while Boss Bass dives into the water and until his head pops up they must stop. If done correctly, Boss Bass doesn't hurt the plumbers but are still stuck inside and the player cannot escape except by exiting the level or restarting the game.

===Fast Underground Music==
If the player is overworld and uses a [[Starman]] and goes to a pipe, after the Starman is done, the underground music will play very fast.

To do this glitch, Mario or Luigi must have completed World 2-Pyramid. It will have a "completed" white icon, however, if Mario goes to the left, so that the level is off-screen and back, the icon will turn yellow.
This only works in Super Mario Advance 4. If a Starman runs out in this version, Mario will have a slightly washed-out color palette. This will be fixed if he takes a warp pipe or door, takes damage, beats a level, or gets a power-up (other than a Starman).

If done correctly, Boss Bass doesn't hurt the plumbers but are still stuck inside and the player cannot escape except by exiting the level or restarting the game.
