Roger's arms can move but his "belly button" is fixed in place.
Pieces like Roger, Sylvester, Petya, and Pingo just stay at home because the gallery that sells my "Dudes" doesn't want to take them, they just want the regular pieces. I think they feel the colors make them too hard to sell. So the guys just stay on my shelves and watch me work. I'd consider Etsy for them but I'm too worried about the shipping - even with a lot of bubble wrap they could wind up being just a box of shards on arrival.
As for Petya, she's nearly 24" high and would probably never survive shipment. Right now I'm in the process of making her 4 other sisters, all tall like she is.
