someone is turning two

Oh, it's July again and my baby boy is turning two! How fast he's growing:) Therefore, I'm planning to throw him a party. Can you guess what the theme will be from the pictures below? 

They said it all, eh? He's in love with the toy and he can name all the cars living in Radiator Springs :) So, it's only fair that I surround him with his 'muse' with a little twist. It's two weeks till his birthday and ideas are racing in my head. Let's see how it all turns out :)
