Twirlip

Twirlips are enemies that appear in Super Mario Galaxy 2. Their name is a combination of "twirl" and "tulip," describing their motion and appearance. At first glance, they appear as white bud-shaped creatures that resemble onions with two beady eyes. To attack, a Twirlip turns into a pink flower with a yellow center and quickly spins around the area like a drill. It does this from time to time.

While twirling, a Twirlip can be damaged only by stomping on its head, which makes the Twirlip drop a coin. In a Twirlip's bud form, Mario or Luigi can use any attack method to defeat it, which makes the Twirlip drop three Star Bits unless stomped. Yoshi can also eat a Twirlip, but only while it is in bud form. In some galaxies, Twirlips can also be found on a Bonus Planet. When shot by a Star Bit from the Star Cursor, they get stunned in place for a moment.

In their opened form, Twirlips can actually defeat another Twirlip when the latter is stopped by a Co-Star Luma and the two Twirlips collide.
