In a Piranha without injury

From Glitches

From the game Super Mario RPG for the Super Nintendo

Go to Bean Valley where the flying shy guy waters the piranha plants arranged in a circle. Before he waters it, jump onto a piranha plant. When he waters it, you'll be inside of the plant (although it may not look like it). The piranha plant will move around but not initiate battle with you. However, if you move or jump, you'll start fighting with it.
