Tentspear

The Tentspear is a weird enemy appearing in Pikmin: Evolution Unleashed. It initially appears as an insect-shaped mass of dark tentacles, and when Olimar approaches it, it reforms itself to copy his appearance. After assuming Olimar's likeness, it holds a spear with a red eye on it in its right hand and its left arm becomes a tentacle with a mouth at the end of it. The Tentspear's left arm can shoot three balls of red acid at a time. The acid is potent but cannot melt Iron Pikmin.

Olimar's notes

 * "This is a disturbing creature, and I would prefer not to encounter it again, as interesting as studies on it would be. It copied my appearance when I approached it, and after that, it started to attack me. I'm not sure how well I'm going to sleep tonight, knowing that such a creature as the tentspear could mimic my likeness and twist it so that it was faceless. I am very happy to have befriended the Pikmin so long ago."

Louie's notes

 * "Inedible. If attempted, may cause extreme sickness or worse."
