Virtual Aquarium on Finding Nemo DVD

When I first heard about the virtual aquariums on the Finding Nemo
DVD, the first imagery came to mind was the aquarium in the dentist
office.  I was really disappointed when I found that the dentist's
aquarium was not one of the virtual aquariums.  The ocean scenes are
good to have, but they don't look like any aquarium to me. The
dentist's aquarium was one major set in the movie, I couldn't believe
PIXAR would omit it.

Anyone feel the same?
