Super Mario series
Peepas appear in Super Mario 3D Land, marking their first video game appearance, found in Ghost Houses, they don't make any physical attack when Mario (or Luigi) is near, so they appear as an obstacle instead of an enemy, the only way to defeat them is being Invincible Mario (or Luigi).
Peepas are very different from Boos. Peepas don't rotate they just stare and revolve around eachother, they're not shy like Boos. First appearing on World 3-Spooky House, Peepas will try to stop Mario/Luigi from escaping the house by revolving around them in certain areas, this makes it harder to navigate because again--Peepas don't get embarrassed when you look at them. Starman is the only way to defeat these type of Boos.
