Mutant Anemones

Mutant Anemones are Captain Filch's Mutant Slaves, created by Captain Filch to serve him. Their first and only appearance is in Raphael Meets His Match.

It seems they're able to talk, as one of the Anemones whispers to Captain Filch that April was trying to contact the turtles.

Most of the Anemones were defeated by being thrown out of the McDonald Crump's ship.
