Mine

Floating Mines are objects that 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 Super Star 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.

Floating 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 Floating Mines on their heads. If the Floating Mines hit someone, they do not explode. They simple knock them unconscious.

Floating 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 Floating Mines surround the arena, Mario (or Yoshi, Luigi, or Wario in the remake) has to throw Bowser into one of the Floating Mines to defeat him. If the player jumps into one of the Floating Mines, they would take two wedges of damage.

The Floating Mines also appear in Super Mario Galaxy. In this game, they are usually immobile, but sometimes move. They can be defeated if they are shot with a Star Bit. They also appear in Super Mario Galaxy 2, where they are exactly like the ones in Super Mario Galaxy. In this game, Yoshi couldn't eat them. Some of the Floating Mines may release Coins, 1-Up Mushrooms, or Star Bits. In Deep Dark Galaxy and Cosmic Cove Galaxy, there are Floating Mines with eyes. These Floating Mines can regenerate themselves after their detonation.

Floating Mines also appear in Super Mario 3D World in the form of a green spiked ball with yellow spikes. They first appear in Clear Pipe Cruise. They are in the interior of Clear Pipes blocking parts of them. Some Green Stars are among Floating Mines; if the player hits a Floating Mine, they do not only take damage and lose a power-up, but they are also ejected backwards in the pipe, so its destruction is necessary to pass. They can be destroyed by a Fireball from Fire Mario, Invincible Mario or White Tanooki Mario.

Mines reappear in Captain Toad: Treasure Tracker.
