Volatile Dweevil
Mandarachnia explodus
The Volatile Dweevil is a kind of enemy in the Pikmin 2 game. They resemble walking bomb-rocks except that they are dweevils. Unlike other Dweevils, they will start to detonate as soon as they start walking. They are also known to drop from ceilings. The only way to kill it is to run and wait for it to detonate, although if you are in peril you may use ultra-bitter spray to petrify it and then kill it. You will at least get nectar, or possibly spray.
