Starnacle

The Starnacle is a rare octopus-like enemy in. It has three equally-spaced pink tentacle-like arms and a large green eye on its main body. Its eye closes and its arms retract when the eye is hit with a Pikmin. It is found frequently in the waters of Pollution Pool, where its arms act as an obstacle to the player and their Blue Pikmin.

Behavior
The Starnacle's only purpose is to block underwater passages. Aside from that, it doesn't do anything and is harmless. When a Pikmin is thrown at its eye, it will retract its tentacles, leaving enough room for Olimar and his Pikmin to avoid the creature and keep going in the passage.

Locations

 * Ravaged Rustworks
 * Pollution Pool: This is the only area that they are found in. They mostly serve as enemies to avoid in the water sections, along with Puckering Blinnows and Young Yellow Wollywogs. They also serve as blockages so Olimar can't enter certain areas without the Blue Pikmin necessary to defeat them.

Strategy
There is no way to defeat this enemy; however, it can be stunned for a certain amount of time by simply throwing a Blue Pikmin right into its eye. Once done, it will retract its arms and allow passage until it extends them again.
