Topmini

Micro-Topmen are the smallest members of the Topman Tribe, appearing only in Super Mario Galaxy and its sequel as enemies.

Super Mario Galaxy
Micro-Topmen first appeared in Super Mario Galaxy where they were enemies in several levels where Topmen appeared (mostly in the Battlerock Galaxy and the Dreadnought Galaxy). They were typically found in groups of two to three Micro-Topmen and they tried to spin into Mario which would simply push him backwards. This move, though incapable of damaging Mario directly, can push him into some sort of hazard which will damage him.

Micro-Topmen can only be defeated by a Spin which will cause them to explode into one Star Bit that Mario can collect. However, they could also be destroyed by flinging a Star Bit at them, and would give three Star Bits instead of just one. In many areas after the Micro-Topmen are defeated, a hole will appear and more of the enemies will emerge from it.

In the Buoy Base Galaxy only, Micro-Topmen can be released from a special Topmen Generator and they will attempt to knock Mario into something dangerous.

Super Mario Galaxy 2
They appear in Super Mario Galaxy 2 in the Space Storm Galaxy. They behaved just as in the previous game.
