He sooo deserve a cracker this year, so want to go all out. We can hire a venue so he can invite anyone, but he definately wants Ben 10. I can't see any entertainer accomodating that, so we are going to have to gem up on our Ben 10 knowledge.
Ideas so far are...
Ben 10 pass the parcel (I realise this will get very boring for 8 yo's after about 3 minutes!)
Oh, that was it...thought I had more than that!! See I'm desperate! HELP!
