In Pikmin: The After Years
The Snacktus is an invincible but stationary enemy encountered in Pikmin: The After Years. It resembles a cactus in appearance and shape, and when approached, the beast will reveal its smiling face. It will crush and then eat Pikmin that get close. The Snacktus can not be harmed, explosions merely stunning it, and Pikmin that come in contact with the spines covering its body will be impaled and instantly killed.

In Pikmin 3: The Dweevil's Revenge
In Pikmin 3: The Dweevil's Revenge, the Snacktus is a relatively harmless enemy appearing at Dweevil Desert that merely impales Pikmin that touch it. It is vulnerable only to a leader's punches, or a bomb rock's explosion, although this can not be seen normally, and its remains lose their spikes to allow for safe carrying.
