Appears to be the cheapest instock.
Next cheapest I could find was Gameplay @ £7.98, but it's out of stock.
"Shaun the Sheep is a loveable fluffy animal that does what he can to help out his friends and the Farmer. In this game for the Nintendo DS you play as Shaun, who has to rescue the Farmer's toupee from the other mischievous animals on the farm. Who has stolen the toupee, and can you get it back to the Farmer in time for his date?
The game features all the kid-friendly humour that Aardman is best known for, coupled with a pick-up-and-play gameplay mechanic that appeals to players of all ages.
In the Story Mode, you adventure through the farm in search of the Farmer's missing toupee. Mini-Game Mode offers a variety of different tasks that you can beat your top scores on, and a special Colouring Book Mode allows players to get truly creative.
In the Story Mode, you get to meet up with familiar faces from the TV show, including Shirley, Timmy and Bitzer, as well as those Naughty Pigs. Missions will involve dodging mud balls and scaring chickens, amongst other things. A mission log and mini-map will help you along the way, and playing through the Story will unlock eight new mini-games and lots of collectable items as well. With new music and animations created specifically for the game, Shaun the Sheep: Off His Head! will be a great addition to any child's (or Aardman fan)'s game collection."
