Bommon

Bommon (ボムモン)
A Slime Digimon which has a bomb-shaped body. The fuse on its tail ignites the moment it hatches from its egg and steadily grows shorter, but because it evolves to the next generation before the fuse disappears, nobody knows what will happen if the fuse went out. It possesses a short-tempered personality, and it's said that when it gets in a bad mood, the progress of the fuse gets faster. Because its fuse's "Bachibachibacchin" sparks produce an intense noise, any opponent would be surprised if they were suddenly produced before their eyes.

Etymology
Bom: From Bomb (ボム), a type of explosive device.
