Mother Piyo is Sony’s most festive PlayStation Network character. In October Sony released a Halloween Piyotama skin. Today on the Japanese PlayStation Store, Sony put up a Christmas skin where all the Piyos don Santa hats. Alas, the free skin is incompatible with the North American version of Piyotama. We’ll just have to wait for Sony to put it up at a later date. Even if Sony doesn’t we still got the better end of the stick. Piyotama only costs $2.99 on the US PlayStation Store, it’s 800 yen ($7) in Japan.
