Pukapelly

Pukapelly (プカペリー) is a flying enemy robot from Mega Man 5 that pursuit intruders, appearing in Gravity Man's stage, Gyro Man's stage, and in some stages from Proto Man's Castle and Wily Castle. They stay in place with their eyes closed, and when they open their eyes they move in the direction of their target.

Trivia
A Pukapelly is on the American boxart of Mega Man 5 but there is a turret sticking out of it. However, they don't have a turret.
