The Flat Kirby glitch is a glitch in Super Smash Bros. Melee that causes Kirby to become flatter each time it is used. The glitch occurs when Kirby and an opposing Jigglypuff hit each other with a fully-charged Rollout and the Kirby has just landed from a jump (whereas the Jigglypuff was on the ground the entire time). With the correct timing, Kirby will become slightly flatter. This can be repeated for Kirby to grow very flat and wide, which lasts until he is KO'd. The glitch is easiest to perform on flat stages such as Final Destination.
