Sea Anemone's Ice (イソギンのこおり, Isogin no Koori, lit. Sea Anemone's Ice) is an event in Tomba! 2: The Evil Swine Return.
The Sea Anemone can be found by climbing the tall pole at the base level and glide to the right by having the Flying Squirrel Suit. Start the event by throwing an enemy into the jaws of the Sea Anemone. An enemy will spawn a bit farther to the right which can be tossed.
As soon as the anemone has swallowed the enemy, it will encase itself in ice. Use the Fire Hammer to break the ice and clear the event by picking up its remains, Anemone's Icy Dregs.
