In Pikmin: Sinister Incinerator
Dweenodes are dweevil-like robots in Pikmin: Sinister Incinerator that hop off of Computer Bugs and rush at Pikmin, exploding upon reaching them. The explosions they create are small and can not kill Pikmin; instead, they knock them over and deflower them. Dweenodes eventually detonate if they do not find a target. They are found only alongside Computer Bugs and may even be the creature's larval form. They are very small, being only half the height of a White Pikmin.
