It's an orangutan.
I've never seen those movies but me and my old girlfriend did meet Keiko,the whale that played Willy. He was at the Portland aquarium. When we went in, they told us, "Keiko only performs when Keiko wants to perform."
So I commented that Keiko was an unprofessional bastard. My comment was met with silence.
Some friends of mine once threw a couple ripped up t shirts in the giant shark tank at Sea World.
I have a history if "incidents" on tours. When touring the Winchester House the tour guide was answering questions by one of the other tourist. The guy was asking about various glass and window panes. He said something like, "That's really interesting. The light goes through it but you can't see through it."
I said, " It's called opaque."
The guide and the guy looked at me like I'd just ate a baby.
