The Japanese PS3 gamers that manage to get their hands on a first-print copy of LittleBigPlanet will also be able to get their own Piposaru Sack Boy.
One of my favorite characters to come out of the Sony camp is the crazy-assed, mind-scrambled monkey Piposaru, of Ape Escape fame. He now joins the ranks of Kratos, Sephiroth, and many others as the newest Sackboy. This Japanese PlayStation page says that the first-run disc preorders of LBP will get PiposaruBoy and a cute little Sackboy keychain as a bonus.
I hope we'll see Piposaru in the U.S. in the future. Something tells me we'll have plenty to choose from via DLC.
Bonus: Did you know that Ape Escape (Saru Get You! in Japan) has some of the most wacky commercials ever? I put a couple of my favorites after the jump.
