Prinny Hentai: Character Profile & Collection

Penguin-like dolls from the Disgaea video game series, and other titles by Nippon Ichi. They are mascot minions. Prinnies explode on impact when thrown, dood. Prinnies contain the souls of humans or demons who lead a criminal life or committed a grave sin, and have to work in Celestia (Heaven) or the Netherworld (Hell) to pay off their debts and reincarnate as something else. It's stated somewhere that you also become a Prinny if you lead a meaningless life. (Source: Danbooru Wiki)
