The tusks are dentalium sea shells that add realism - new. They used to be wooden tusks. Clam Digging has pair of halfman halfwalrus dancing with carved masks and smiling eyes. Their dance fans are colored turkey feathers.  They have beads and clams floating with them and carved halibut and seal swiming in the background. Then reindeer hair and feathers on the heads to give that feal of motion.
