Yes, that's the ones I'm talking about!
From time to time they sell these at the FunParks. Other times they have been given away by the DS when you spend over a certain amount of money. I didn't know they gave them away at the FunParks too - interesting!
Occasionally keychain/keyring figures have also been available to buy through the DS catalogue too. I have a few very old DS catalogues from about 80s-90s which show keychains for sale such as the ape, Romani clowns, Victorian ladies, and others. The most recent example of this was the blue-uniformed Police figure keychains a couple of years ago.
