Prinnies are the adorable, explode-able little penguins from the Disgaea series. They were usually used as weapons by their abusive Lords, but this time, they're the main stars in Prinny: Can I Really Be the Hero?, an upcoming side-scrolling platforming game from NIS!
Someone was foolish enough to steal Etna's dessert. The Prinnies noticed the theft, but didn't say a word for fear of destruction. Etna, of course, found out about the missing treats, but instead of killing all of the Prinnies under her command, she ordered them to get her the Ultra Dessert. The Prinnies have ten hours to get the Ultra Dessert or else Etna will kill them all.
