Not sure if this helps or not. But I've been buying my daughter Palace Pet toys at Target and Toys R Us for at least two years now. For a while some of the pets were even at Build-a-Bear. You could always sneak them into your suitcase and surprise her in Disney!
We have quite the palace pet collection in our house - 3 stuffed animals, several of the really tiny pets and dozens of the ones with the furry tails that are a couple inches tall. And we still don't have them all!
