Pillar

A Giant Spike Pillar is a pillar with spikes from Super Mario World, New Super Mario Bros., and New Super Mario Bros. Wii. It starts descend upon the player at certain times. When it starts, it goes down a little bit and then it comes down fast until it hits the ground, then returns back up to where it started. It repeats this technique continually.

However, it is indestructible, so the player can't defeat it, making the goal to only safely pass it. Without any item influence, the player will die on contact with the obstacle. With a Mushroom, the player returns to regular form, and with a Fire Flower, Ice Flower, Propeller Mushroom, or Penguin Suit, the player returns to Super Mario. If the player has a Starman or Mega Mushroom, they will be unaffected.
