Flaptack

The Flaptack is an enemy that appeared in Super Mario Galaxy 2. They are large, round, blue and yellow birds that have yellow spikes on their heads. When they see Mario or Luigi, they will hover over them, then flip over and try to stab one of the heores. If they miss Mario or Luigi, they will be stuck in the ground for a few seconds and one of the heroes then can jump on them and get a coin. Flaptacks can also be defeated by jumping then spinning while they are in the air flying to get 3 Star Bits. They can destroy clouds made by Cloud Mario/Cloud Luigi with their spikes. They appear in galaxies like Fluffy Bluff Galaxy and Flash Black Galaxy.

Trivia
The Flaptack's name is a portmanteau of flap and tack, with flap referring to their wings flapping, and tack referring to the spike on their heads.
