In Pikmin: The After Years
The Steam Goolix is a species of cell puddle in Pikmin: The After Years that has a body composed of gas instead of liquid and can float because of it. At first sight, this creature appears to be the two nuclei floating about, but it does have a white cloud for a body. It has no direct way to injure Pikmin, but it does have the ability to knock away Pikmin that are attacking it by banging its two nuclei together. This attack flings Pikmin quite far away and affected Pikmin can land in hazards or near other enemies. Steam Goolixes chase after Pikmin, so these can be particularly annoying and hard to avoid, especially if there are multiple. Leaders themselves can not defeat Steam Goolixes, but Pikmin can. Both of the two nuclei are vulnerable to damage from Pikmin. If the area is safe, the white nucleus can be attacked since it is easier to hit. It bounces Pikmin away when struck, so it should not be targeted if the surrounding area is not cleared. The other nucleus is harder to hit, but it's safer since it does not scatter Pikmin as easily, and Pikmin can cling onto that nucleus. Pikmin can be recalled just before the two nuclei smack together to prevent them from being scattered. However, it is easy to hit the bigger nucleus accidentally, so care must be taken to avoid doing so.
