This enemy is a much more powerful version of the Green Gel Tree. It fires 15 consecutive wave attacks that deal rather high damage. The projectiles move at a low speed, but slightly faster then the Green Gel Tree's attack, giving the player the advantage of dodging, if the player can do so, as the boss's waves spread at a 120 degree angle with a moderately-high firing rate. A hit and run tactic using high-powered and high-ranged weapons, such a Gunner equipped with a Bazooka with a Catapult's Card and a Critical's Card works well against it. Ice, Fire, and Poison type weapons also take care of it easily.
It is the one of the four biggest Trees in the game, and it is the only one among them that is in an underwater stage.
