Any ideas for an 8 yo Ben 10 themed party...

[IfYouCanKeepYourHead]

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!

DS had one for his 5th birthday

I made Ben10 tattoos (you buy paper that goes through your digital printer)

Ben10 name badges (got them laminated and stuck badge backs on the back)

a Ben10 cake (it was an omnitrix made with sweets .. really easy)

kids don't need the whole thing themed just bits and pieces

We downloaded the Ben10 themesong onto Ipod .. you could do musical statues / chairs

Ben 10 party stuff.

Fab ladies, thanks...any ideas for games?
