Shurubon

Shurubon are orb enemies in Mega Man Zero 2 that are almost like the Up-n-down of the classic series. They appear in the stage of Burble Hekelot and jump up and down in pits. If Zero attempt to jump the pit without deeating them, they will hit him. If they are destroyed, another one will appear soon after. They drop a Cyber-elf when some are defeated.
