There are 3.7 trillion fish in the ocean. They're looking for one.

Nemo, an adventurous young clownfish, is unexpectedly taken from his Great Barrier Reef home to a dentist's office aquarium. It's up to his worrisome father Marlin and a friendly but forgetful fish Dory to bring Nemo home -- meeting vegetarian sharks, surfer dude turtles, hypnotic jellyfish, hungry seagulls, and more along the way.
In Finding Nemo, consciousness is carried by animals — a plane of “anthropomorphic ocean”. The story fights on E8/E9 of the E0–E14 reality ladder, compressing family, growth, community, trust, identity.
Films fighting at the same level of reality, about the same things.
