My headcanon is that they only use bomb rocks when protecting their brood, so the ones we see are males who already bred and have eggs to guard

when they explode they spread their semen around in the air like spores. You can rest uneasy knowing that whenever a Volatile Dweevil blows your Pikmin up, he also came all over you too.

My headcanon is that the bomb only activates when there's a threat, Olimar would definitely kill them if they didn't have a bomb attached to them

I think even Olimar himself was stumped as to how this species even propagates/survives considering they are constantly blowing themselves up.
