Okay this isn't my cup of tea, but is a good price for thos looking for a childrens orientated game.
Keep those cheeky monkeys out of the way for an afternoon, and when they're bored trade it in at blockbuster for a slight profit?!

Cheapest I can find it online/offline.
"Surf's Up is an exciting arcade surfing and extreme sports video game. The action is set at the annual "Reggie Belafonte Big Z Memorial Surf Off," where surfers from around the world are ready to risk it all for glory. Players will experience the rush and thrills of surfing in exotic surf spots around Pen Gu Island and can rip it up and play as one of 10 characters from the film, including Cody, the young challenger from Shiverpool; Tank, the merciless champion; or Big Z, the surfing legend from the past. Only by mastering and understanding the waves can the player become not only the new champion, but a true surf legend."
Not the best reviews in the world agreed, but it's hardly going to compete with Halo3.
Hope this helps to keep a couple of cheeky monkeys busy for a few hours
