Prinny 2: Dawn of Operation Panties, Dood!

 is a platform game developed and published by Nippon Ichi Software on March 25, 2010 in Japan, on December 15, 2010 in Europe and on January 10, 2011 in North America for the Sony PSP. The game featured 2 additional levels and 1 add-on item, but with the shut down of the PSP frontend online shop they can no longer be obtained on the original console. The PS Vita release of the PSP version allows to download all of the content, but to be able to get everything on the original hardware a Sony PS3 is needed (see below for details).

How to obtain
The DLCs can still be obtained on the PS Vita release from the Playstation Store or, on the PSP, by purchasing the PSP version on a Playstation 3 system and then transferring them on the handheld console.
