Need to buy something for two great- nephews 5 and 6. Lovely boys but don't see them very often and when I do they're just bombing around and don't seem to be into anything in particular. They're definitely not bookish if you see what I mean. I have asked and been told "oh they're happy with anything!" Budget is £10-15. Don't really want to do lego/playmobil as have done this to death in previous years. Sorry - completely clueless with boys I'm afraid.
