For the Yeti’s arms I cut the Dunny’s arms in two, and found that the circumference of the arms match up exactly with the base of the Dunny’s ears. I had one of those Dunny hat accessories that come with the 7″ Munny toys, so I took the ears off that and attached it to the Dunny’s hands, ran some wire through it so I could bend it into position, and used polymer clay to build up around it.
