Mine

Mines first appeared in Super Mario World as spiked balls that drift in the water in various levels. They follow the current continuously and pulsate with spikes. Yoshi can step on their spikes harmlessly and a Starman can defeat them. In the Sunken Ghost Ship, many are in freefall, making it difficult for Mario or Luigi to move around. They can also be eaten by Yoshi.

The Mines reappeared in Super Mario Land: 6 Golden Coins as a spiked ball spinning around a bubble in the final stage of the Mario Zone; these floating Mines behave identically to Ball 'n' Chains and Roto-Discs.

Mines also appear as a projectile in Mario Party 6, in Sink or Swim. While three other characters are swimming in a body of water, one player tries to drop mines on their heads. If the mines hit someone, they do not explode. They simple knock them unconscious.

Mines play a vital role in defeating Bowser in Super Mario 64 and its remake. In the final arenas of Bowser in the Dark World, Bowser in the Fire Sea, and Bowser in the Sky, where the Mines surround the arena, Mario (or Yoshi, Luigi, or Wario in the remake) has to throw Bowser into one of the mines to defeat him. In the remake, if the player jumps into one of the mines, they would take two wedges of damage.

The Mines also appear in Super Mario Galaxy. In this game, they are usually immobile, but sometimes move. They appear in lots of galaxies such as Battlerock Galaxy. They can be defeated if they are shot with a star bit.
