Oh yes, if you go look in the items section of the Japanese LBP Site you can find out what sackboy costumes that should be making their way to the Japanese Playstation Store this week. Or you could read this; there's a Toro (based on the main character of Mainichisshyo), a shark, chameleon, penguin and a gorilla. Or you could even look at the image below. We're really spoiling you for choice, aren't we?

Hopefully we'll be seeing these in other territories too. Personally, I really want that penguin. Penguins are awesome.
