Mario Bros. is a stage in Super Smash Bros. Brawl. It is the only stage at which a player can attack R.O.B during all-star mode. It features a classical game, where turtles and crabs come out of pipes. Both can be picked up, only if stalled. There is a POW box at the bottom that can stall some, or attacking from the underneath can stall one. If one is stalled, and left go, it changes colors and goes faster than the previous. These colors end at purple, where they are the fastest.
