Fossas

The Fossas are the main villains in the movie Madagascar. They are the enemies of the lemurs.

The fossas first appeared when they crashed King Julian's party and attempted to eat Mort, but when Alex noticed a spider on his back, he scared the fossas away.

Then when Marty convinced Alex to go on the ship with them, the foosas appeared once again and attacked Marty, Melman, and Gloria. Private and his fellow penguins came to the three animals aid, and Alex showed up and clobbered the fossas and scared them away once again. After that, the fossas never bothered the lemurs, Alex, and his friends anymore.
