Dweenode
From Pikmin Fanon
A dweevil-like creature that hops off Computer Bugs and rushes at Pikmin, quickly exploding. The explosions may be very small, but they knock Pikmin over and remove their flowers in an instant. Dweenodes spontaneously combust so there is no need to worry about them sticking around for too long. They are only found alongside Computer Bugs and may even be the creature's larval form.
