We saw Nemo outside of the Living Seas in Epcot. It's like a big plastic Nemo on wheels that the kids can pose with, hug, etc.
The Nemo exhibit in the Living Seas was wonderful. My daughter loved "finding" nemo and looking at the Jelly fish and the sting rays. And there were lots of "Dories" for her to make whale sounds at. LOL
There's also lots of Nemo stuff at the gift store there. My littlest got a stuffed Squirt.
