1. Neon the fish tries to go to a party with some whales, sharks, and swordfish in a dark cave, but is told he cannot come because he is small and lacks their distinguishing features like a big mouth, teeth, or nose.
2. When they arrive at the dark cave, the other sea creatures cannot see because it is too dark.
3. Neon has an idea and is able to help the whales, sharks, and swordfish see in the dark cave, showing that despite his small size, he is special. The others then cheer for Neon.
