Honestly, Bob-ombs are even funnier, considering Paper Mario.
Every Bob-omb variant, including the unaffiliated Bulky Bob-ombs, & Bob-ulks, when hit with ANYTHING Fire, Electricity & Explosions, will themselves, explode.
A curious example is how Bombette in PM64 will get "injured" like other partners if she takes damage (They're normally not directly attackable in PM64.), but she explodes when doing so, at least in some circumstances, IIRC. I forget if that's the case for like, Body Slamming a forward-speared Spear Guy or just Body Slamming a Lava Bubble or such.
But unlike other Bob-ombs (Some friendlies who escaped Koopa Village who could do explosions & survive just fine for celebration.), other Bob-ombs will straight up die/disappear entirely when they explode.
Where this gets silly is Duplighosts:
If a Duplighost turns into a copy of Bombette & Watt uses Mega Shock, a non-damaging, non-contact move that can MAYBE inflict Paralysis, likely even if you don't do the Action Command, all the Bombette-copy-Duplighosts WILL explode.
& again, they explode to ANYTHING Fire, Electric or Explosive.
So Bombette can survive exploding, but copies of her CAN'T. Are PM64 Duplighosts just really bad, lol?
Admiral Bobbery (& Doopliss, when copying him.) doesn't have this vulnerability strangely.
I can't remember if regular Bob-ombs exploding can cause a chain reaction of others exploding.
It's even sillier with Bulky Bob-ombs/Bob-ulks, which spend like 3 or 4 turns applying buffs to themselves (& 1 just lighting their fuse & starting to run around in a panic.), but who's explosions are AoE enough to affect the whole battlefield.
They'll do this waste of time no matter what, even if they have the burn status, which will deal 1 Fire damage to the Bulky Bob-omb/Bob-ulk at the end of its turn, causing it to explode early.
Which they means set each other off. Luckily, their base attack is 2, but still.
It means if you decide to like, First Strike a Bob-ulk with Bobbery's Field Move, it'll detonate the first Bulky Bob-omb or Bob-ulk... which will make all the others explode, too, all before even the first turn has finished!
Again, only 2 base attack, but since they're often in groups of 3 or 4. (Plus, I think Bob-ulks are stronger.) Enjoy the fireworks! (& pain.)
Notably, that reminds me of a fodder feat: Bulky Bob-ombs in the audience can explode (Which has a live seat count & can hold up to 200.), which, IIRC "blows away" all the other audience members, which can include Shy Guys, Toads, Luigi, Punis, Dull Bones, Pirhana Plant, etc.
With the AoE & mass of the audience members sent flying it might be good. Potentially higher if they're destroyed.
