Ideas for 6 yr old boy

[BeaLola]

Looking for inspiration as has birthday and Christmas close together. Hasbike, scooter, lots of lego and playmobile and tablet so what else ?

My DS like marble runs- you can get some quite complicated ones. They also like science kits - electricity, magnets, etc.

My DS has shown interest in every toy in every ad break Disney Infinity and the VTech camera. He will definitely be getting a dress up costume (Spiderman or Superman) and a new skylander. I'm also on the lookout for a good board game that the whole family can enjoy. He loves Cluedo and Monopoly so I'd like something similar.
