Query: LocoRoco's the big winner among Xmas gifts!

Even though it was one of the smaller, filler gifts, LocoRoco's proven to be the most addictive present so far for our two kids, ages 7 and 9. Definitely will take up most of their time on the PSP for the near future. Cute, challenging, and fun, fun, fun!
