Planterrian

The Planterrian is a War Mode, Post Oof Spirit Enemy. It only spawns fairly uncommonly in the Underground Jungle, below the cavern layer.

A.I
The enemy will float into the screen. It performs a series of attacks.

1: The Planterrian will travel slowly towards the player while spinning and shooting Planterrian Spikes that deal 100 / 200 damage from all of its petals.

2: The Planterrian's petals will close its main body. The enemy will reflect any damage in this form. It will still, however move, albeit slightly slower.

3: The Planterrian will perform a super fast dash attack at the player. It will shoot Planterrian Spikes as fast as the Star Cannon, Minishark in Expert Mode, Megashark in Master mode, Chain gun in Destructomode.

4(Master mode and above only) The boss will shoot Planterrian Magic at the player. This deals 200 / 400 damage when the player hits it.

5: The Planterrian will teleport and then repeat the process all over again.

Drops
The Enemy will always drop good items that can be used for War Mode Post Oof Spirit items. The Sporesnake is an example of this.
