Spike Top

Spike Tops are similar to Buzzy Beetles, except their shells are red and have a single spike projecting out of the top, making them impossible to be jumped upon, while still being resistant to fire. They crawl around walls in Super Mario World, New Super Mario Bros., and Super Princess Peach. They are also one of the few enemies in Super Princess Peach resistant to Perry. They are blue in Super Paper Mario and in Paper Mario: The Thousand-Year Door, where Red Spike Tops appear as a sub-species.

Quite interestingly, Super Princess Peach refers to the Spike Top as the Mecha-Spike Top. Despite this name, the Spike Tops of Super Princess Peach look no different than Spike Tops of other games, and therefore do not appear to be mechanical. Super Princess Peach also introduces an angry variety, the Mad Mecha-Spike Top, which can stretch out its spike to attack foes.
