Present for 8yr old boy?

What should I buy my 8 year old nephew - despite asking his parent we've received no suggestions! He wouldn't appreciate anything educational - will want whatever the latest thing is. Looking to spend up to £40. Thanks!

Have an 8 year old DS but don't know what the 'latest' thing is. They are really into Nintendo DSs at that age.
