Sea Anemone is an enemy which appear in the second game. It has the ability to suck in objects. If it catches Tomba, it will deal some damage and then spit him out after a couple of seconds. There is totally four Sea Anemones in the game; two of them can be found in Pipe Area and the other two in Ranch Area.
In order to defeated it, another enemy must be tossed into its mouth. It will decease and shield itself with a barrier of fire or ice. When the barrier is removed, it will leave behind either Anemone's Hot Dregs or Anemone's Icy Dregs depending on the type of Anemone. Those items are part of the Sea Anemone's Burning Dregs and Sea Anemone's Ice events.
