Etsy retailer Makosla Creations makes dragons. They’re forged from polymer clay and many of them like to sit on your shoulder.
The dragons ship worldwide from Canada but are fragile. They’re not really suited to LARPing and I think you’d be a brave cosplayer, or expecting a quiet con, to try and make it through a day in the crowds without a bump. These little critters are art.
