Ghastly Empress Bulblax

The Ghastly Empress Bulblax is a boss that first appeared in the game Pikmin:The After Years. It is the soul of a deceased Empress Bulblax. Its markings and general features are similar to those of the Ghostly Bulborb, but its body is much larger and composed of five distinct segments; its comparatively tiny legs dangle above the ground. It will occasionally birth larvae. This Bulblax can go through walls and the only way to be able to hurt it is by reflecting light at it using the Reflector.

How to Kill
To defeat this enemy you need to shine light on it to turn it solid. Then throw (preferably Purple) Pikmin onto its face and call them back before it throws them off. After shaking Pikmin off, the boss rolls from side to side across the chamber in an attempt to crush its aggressors, going through walls, and giving birth to larva. It CANNOT be petrified. Instead of being able to carry its body to the pod, it will disintegrate into Dark Matter.
