In Pikmin: The After Years
An Eyevine is an enemy appearing in Pikmin: The After Years. They are intricately colored one-eyed plants that block geysers and holes to delve deeper into a cave. They are teal and yellow with a red and black pupil. Though they don't attack Pikmin, they can be nuisances. They are one of the many enemies influenced by dark matter. The only way to kill it is to attack its eye. Upon approaching it, it will shut its eye, its only weakpoint, rendering it invulnerable. Fortunately, chestnuts can be thrown at it from afar to hit its open eye. Doing so will instantly kill it, and instead of it dying on the ground, it will disappear into dark matter. These enemies are based on the vines that block entrances and doors to other areas in the Forbidden Woods in The Legend of Zelda: The Wind Waker.

In Pikspore
In Pikspore, the Eyevine is an aggressive creature that blocks access into holes. They have many tentacles, and teeth, and are a vivid green. They swat Pikmin away from themselves and can also crush them. A throbbing organ on its back serves as its weakpoint, although the organ will periodically ooze red liquid that covers Pikmins' stems, suffocating them. When killed, it will writhe around and melt into a red, bubbly foam.
