Electro Goolix

The Electro Goolix first appeared in Pikmin:The After Years. It is a mildly tough enemy because of is ability to instantly kill every Pikmin except for Yellow Pikmin, which will drown instead. Because, as can be seen in the picture, there is still a gelatinous membrane, which will still drown any non-blue pikmin (unless they get electrocuted first).

How to Kill
The only way to kill this enemy is to continuously toss pikmin on its large nucleus: use yellows if you want to minimize pikmin deaths, purples if you do not have good aim, or any other color if you feel like being psychopathic. using bulbmin is wise because they are immune to both water and electricity.

After Years
In Pikmin:The After Years, it is a recurring enemy.
