Spikes are a hazardous object which appear in Super Mario World and its remake Super Mario World: Super Mario Advance 2.
Description[]
Spikes are wooden stakes with a pointed edge giving it the shape of a pencil. They only appear in castle and fortress levels, specifically only Chocolate Fortress and Larry's Castle. Spikes come out from either the ceiling or floor, similar to a Skewer, but unlike them, most Spikes do not completely push their way out from one side to another, leaving them vulnerable to attack. if Mario or Luigi touch a Spike from the top, they take damage, due to its pointed edge, but if either brother touches the side, they are unaffected.
