Activa yoghurt...and No you can't get one....annoying isn't it cause I wanted one as well......I am even willing to kidnap a small child to keep in the suit if I can get one as well.
That would be the Danone Activa Yogurts!
You can now get an Inner Self blue monster toy with two proofs of purchase as I picked up a leaflet in my local Sainsbury's just yesterday and was most excited by the prospect of having my own little fuzzy blue Inner Self! :o)
