A spin-off of the Disgaea series
As a Prinny, the player is tasked with tracking down the ingredients for the Ultra Dessert for Etna. She gives the 1000 member squad ten hours to track it down, threatening to kill them all off should they fail. As such, you do not play as any unique prinny in particular, though the speech of the one you play is always the same. Etna only issues one Scarf which prevents a prinny from exploding once worn, and as such, once the Hero Prinny is killed in one way or another, another of the 1000 is simply tossed up to the plate, wearing the single scarf.
One of its unique features is that, owing to the game's high difficulty, the player gets 1000 lives.
There is an upcoming sequel entitled "Prinny 2: Dawn of Operation Panties, Dood!" in the works.
