Mokumokumo

Mokumokumo (モクモクモ) is an enemy from Mega Man & Bass, a small robot that is surrounded by smoke. If a Mokumokumo touches Mega Man or Bass, it will interfere with their jumping, making it difficult to avoid enemy attacks and obstacles such as pitfalls. They appear only in the first room of Tengu Man's stage. The Oni Robos in the same stage and Cold Man in his boss fight can summon them.

The GBA version of Mega Man & Bass calls these enemies "Cold Mists".
