Penpen

Penpen (ペンペン) are small penguin robots in Mega Man 3. They mainly appear in Gemini Man's stage (before Doc Robot), and come out of the Penpen Maker. Later they'll be in the water area of the first section of Dr. Wily's castle, where they move up and down until you're close--then they swim toward you.

In Mega Man: Battle & Chase, there are unnamed penguins that act like Penpen.



Penpen Maker
Penpen Maker (ペンペンメーカー) is the "mini-boss" of the Gemini Man stage (before Doc Robot), and there are two of them. Both are dealt with by hitting the eyes.



Penpen EV
Penpen EV (ペンペンＥＶ) is a upgrade of the Penpen. In Mega Man 8, it mainly dwells in Frost Man's stage, and many appears from the ice blocks that emerge from Whalaship. It spins around, and can be pushed aside with a few shots. But if left alone, it will face Mega Man, get on its belly, and do a short jet boost to do a fast slide toward him.

Trivia
In the Taito game, Graffiti Kingdom, one of the enemies is a "Frappenguin," which sort of resembles the Penpen Maker.
