Rush Mammoo

The Rush Mammu (ラシマンムー) is a giant mammoth-like boss Reaverbot, a larger version of the Mammu. The Rush Mammu is the guardian over Sera's prison on Forbidden Island. MegaMan only comes up to its ankle/knee. It attacks shooting ice blocks from its trunk, creating a shockwave with a jump, a charge, and shooting energy blasts from its belly.
