When we went into the giant fish tank that you can walk through, we saw this polar bear trying to eat a seal, but it couldn't get to it because there was a big wall of glass inbetween it and the seal. It was funny to see though.
I also used this thing that lets you see whats going on from a security camera, and spied on people. It was hilarious because they didn't know that they were being seen, so their faces were just funny.
I had a lot of fun.
