ALso, It looks like the bottom of thhe figurines is simular to .... ah whatcha call it... AH YES! Funkey USB.
Quick summary of what that is: Funkeys are collectible ffigurines that you can pput in Funkey USb posrt, and then you can play in diferent areas of a online world. A new funkey gives you new Areas.
I have seent he bottom of the TamaTown figures, and find that they look simular to the bottom of the Funkeys.
NOW. WHY IS THIS IMPORTANT?:
This can be done on Purpouse with Funkeys! Actually, if you lick the bottom of a Funkey, it is possile to get other Funkeys. If you search a bit on a search engine, you mght even find a chart.
I wonder if this works with Tama ID figures...
