Pillar

A Giant Spike Pillar is a large column with spikes from Super Mario World, New Super Mario Bros., and New Super Mario Bros. Wii. These threatening traps only appear in castles, usually hidden in the floor, ceiling or also in walls. They move slowly for some seconds to rise suddenly from the surface, smashing almost anything on their way. After some seconds later, pillars move back to rise again.

Pillars are indestructible so the player can't destroy it. The player has to avoid it because of its spikes, or else if the player touches it in a small form, he/she will lose a life, unless if the player has a mushroom, he/she will turn back to small form. If the player has a different power-up and touches the Giant Spike Pillar, he/she will turn back to normal, except what happens in Super Mario World. If the player has a Starman or a Mega Mushroom, he will be immune by touching the pillar while in Invincible or Mega form.
