Mine
Mines first appeared in Super Mario World as spiked balls that drifted 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 behaved 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 unconcious.
The Mines also appeared in Super Mario Galaxy. In this game, they were somewhat immoble. They appeared in galaxies such as Sling Pod and Bubble Breeze Galaxies.
