Icicle

Icicles are pointy pieces of ice that have sometimes appeared in the Mario series. They first appeared in Mario Bros., as enemies that attacked by dropping from the ceiling, that first appear in Phase 16.

Icicles also appear in other Mario games, such as Super Mario 64, but have no function, and do not affect gameplay.

They also appear in an ice-cave level in Super Mario World 2: Yoshi's Island. They have the same attack as they did in Mario Bros., and whacking an egg at them would cause them to fall down from the ceiling. They would also hurt the player if they touched an icicle while it was still attached to the ceiling.

Wario has met icicles as well in Wario Land: Shake It!, in the level Slipshod Slopes. They appear in a cove part, and seem to be gigantic. When executing the Earthshake Punch, these big icicles will fall down, and crush any enemy underneath (defeating 5 enemies with those icicles is also a mission in that level). When Wario hits a falling icicle, he'll get hurt. Wario can aslso stand on those icicles as if they are platforms. However, the fallen icicles will break after a short time. when broken, new icicles will grow on the piece of ceiling the old ones were fallen off. there are giant icicles as well in Freezing Fields.
