Peat

A Peat is Dr. Wily's attempt at creating Beat. They rise from tubes in egg form, then quickly hatch and fly at Mega Man. They only appear in the fourth Mr. X stage.

Some of the pipes they raise out of have giant yellow (maybe orange) blocks with an X on them, if you hit it with the Power Adaptor charge shot the box will fall onto the pipe, blocking the Peat from raising out of it.
