Very very very cool. You can buy a penguin encounter ticket for an additional $20 and get to go behind the scenes and hang out with them for about a half an hour. I know the price might be a bit high, but part of it goes to saving them during oil spills and such. The penguins were awesome, they would come up to you, let you pet them, run around, poop a lot, etc. It's a fun hang out that strays from the normal dinner and movie.
