Spike Trap

Spikes are pointy objects that usually cause instant death. These traps appeared in nearly all Mario games, from spin-offs to regular. In Super Mario World 2: Yoshi's Island and Yoshi's Island DS, spikes are found mostly in castles. A more common rough object, a thorn, also appears in the two Yoshi's Island games. In Yoshi's Story, spikes actually move and jump around in the Bone Dragon Pit and Magma Castle. Spikes also appear in Yoshi Topsy-Turvy. Like most other Yoshi games, they will make Yoshi lose a life if he touches them.

There is a Spike Stomp Badge in Paper Mario that lets Mario jump on spiky enemies such as Spinies.
