Rush Mammoo

The Rush Mammoo (ラシマンムー) is a giant mammoth-like boss Reaverbot, and is a larger version of the Mammoo. The Rush Mammoo is the guardian over Sera's prison on Forbidden Island. It attacks by shooting ice blocks from its trunk, creating a shockwave with a jump, charging forward, and shooting energy blasts from its belly.

Strategy
The trunk and the body are separate targets. Destroying the trunk makes it more likely to use the energy blasts. It's best to keep close to it because the energy blasts that it fires zig-zag in unpredictable ways which can make dodging them confusing.

Trivia

 * Mega Man Volnutt only comes up to its ankle/knee.
