Bumpety Bombs (コロコロ爆弾, Roly-Poly Bomb) are enemies from Kid Icarus: Uprising.
Bumpety Bombs are explosive enemies personally created and named by Viridi, and are part of her Forces of Nature. Should Pit battle a Bumpety Bomb and hit one, the fuse on their heads will alight, making them dash toward Pit so that he can be caught in the impending explosion.
Bumpety Bombs appear as enemies. The front of a Bumpety Bomb's body is armored and will resist all attacks, and it will try to rush at nearby fighters before exploding. Bumpety Bombs are vulnerable to being attacked from behind, below, or to grabs. Defeating them or having their timer run out will result in an explosion that will damage other nearby enemies: the player will not be damaged if they defeated it. It will only drop stat boosts if the player manages to defeat it before it explodes on its own.
This pesky bomb has wheels, which means the time-tested strategy of running away doesn't work as well as you'd hope. Be ready for a big blast if this bomb hits zero. Oh, and sometimes the fuse is a little shorter than normal. You'll have to attack from behind to defuse this dangerous foe.
This lucky bomb has wheels! Oh, wouldn't it be tragic if it couldn't chase you? Anyway, as soon as one spots you, its countdown starts. Be ready for a BIG blast when it hits zero! It might also explode before then, too, so stay on your toes. The front is armoured, so attack its back to beat it before it blows up, and you'll get yourself loads of items.
