At the Gloucester Toys r Us they had loads of Go Go Hamsters in stock. There were pleny of all four of the hamsters.
There were also green bags with blanket sets & Green Bed sets (the did have one orange left).
Not sure how available they are in any other Toys R Us stores but I couldnt get any in any of the other local stores including Boots & Argos.
Thought it might be useful to somebody
