Shurubon

Shurubon (シュルボン) is an orb-like enemy in Mega Man Zero 2. They appear in the Forest of Notus (Burble Hekelot's stage) and jump up and down in pits. If Zero attempt to jump the pit without defeating them, they will hit him, getting on the way of his jump and risking to make him fall on the pit. If they are destroyed, another one will appear soon after. They drop a Cyber-elf when some are defeated.
