This video was taken on my phone a few weeks ago - to explain the low quality video, but Hana played with this shell for about 10 minutes until we made her leave it because she got so frustrated. She pushed it around, clawed at, and tried to open it with her mouth. We had never seen her so interested and so determined to get whatever was inside. The high pitch yelps are very unusual for her. I will try to post both short segments I caught with my phone.
