The Flop Box is a glitch on Super Smash Bros. Brawl, discovered and posted onto the internet by TaleOfTheToaster. It is a glitch in which the player sets off a drop box on a stage builder stage, then walks or slides down a ramp which is situated next to it (it will not work if the player runs off), and the player may randomly teleport to the KO Barrier beneath. It is confirmed to work with Mario, Luigi and Lucas.
