Amenhopper

Amenhopper (アメンホッパー) is a water strider-like robot that appears as an enemy in the stages of Launch Octopus and Sting Chameleon in Mega Man X. It moves by skidding on water surfaces or by doing short hops on dry land. Amenhopper was originally used for agricultural work, spreading fertilizer on the ground. As a Maverick, its fertilizer is replaced by small bombs that it will occasionally drop from its body.

Etymology
Amenhopper is a combination of the words "amenbo" (Japanese for water strider) and "hopper".
