New residents in our Rainbow House

So in our Rainbow House (fantastically called by our little Bear as its our pot of gold at the bottom of the Rainbow) we have a playroom... I've just tidied it up and put away all the toys obsessively back into their correct places (!!!) ...I know it's boring, but who wants to open up the wooden train track to find a Mr Potato head ear?! ...so I was thinking, what super cool thing might make my kidlings smile in the morning, and being a huge huge HUGE barbie and ken fan in my youth (and my two are too young and are only just into Happyland) I thought I'd set up the happy land (!) all over the playroom floor to surprise them!!!!
