Polar Bear at the zoo

---

Ok I figured it out:

The bear has a white jug that has orange peels in it. In the first video he has it sqeezed between the cage bars (hidden) and his nose or paws. In the second you see the jug popped out and when he tries to grab it again it pops into the water. I missed the video of the day in number two. It happened so fast. Don´t miss number four as he shows some antics.

First
Second (There is no video worth watching after about 22 seconds on this second one.)
Third
Fourth
