Blu

Old Blu was once the brightest fish in the sea. But as time passed, his color began to fade away. Everyone tries to help Blu be his old self again: the cleaner fishes clean him, the nurse fishes nurse him and the eels bring him nutritious food to eat. But nothing seems to work until a fish named "Puffer" tries a new approach.

"Blu" is a commentary on the importance of happiness on on one's emotional, as well as physical, well-being.
