The Pout-Pout Fish

Mr. Fish refuses because he is described as glum, gloomy, and introverted. He lives alone in a shipwreck and prefers not to get involved in others' problems. He is worried about the effort and risk involved in helping Pip expand her home for her hundreds of siblings.

Both Mr. Fish's shipwreck home and Pip's current home are destroyed, leaving them homeless and shaken. This catastrophe forces Mr. Fish to reconsider his refusal and agree to help Pip find a solution.

Shimmer is a mysterious, wish-granting fish who lives at the bottom of the reef in an abyss. She is rumored to have the power to grant wishes, which is why both Mr. Fish and Pip seek her out, and why Benji also races to find her.

The quest to find Shimmer is mentioned early in the story when Pip suggests visiting her after their homes are destroyed.

Benji kidnaps Shimmer because he does not want the cuttlefish to leave their home in the abyss. The kelp growth is blocking the sun, forcing the pod to relocate. Benji hopes that Shimmer's wish-granting power can save their home, so he takes her before Mr. Fish and Pip can ask for help.

No, Shimmer reveals that she cannot actually fulfill wishes. This is the twist that ruins Benji's plan. It is rumored that she can only grant one wish every few years, but this turns out to be false.

The cuttlefish must relocate because kelp growth is blocking the sun from reaching the abyss. Without sunlight, their home becomes uninhabitable, and leader Marin decides they must move to the reef above.

After Shimmer reveals she cannot grant wishes, Marin disowns Benji for his actions. The cuttlefish relocate to the reef above, but Benji is rejected by his mother for kidnapping Shimmer and causing trouble.

Mr. Fish and Pip rally all the animals they helped during their journey, jellyfish, dolphins, and the mother whale, to confront the kelp problem. Together, they remove all the kelp, allowing sunlight to reach the abyss again so the cuttlefish can return home.

Pip reveals at the end that she wrote a story named The Pout-Pout Fish, and the entire film is depicting the events of her story. This adds a meta layer, suggesting the adventure we watched was Pip's narrative creation.

At the end, after Pip leaves, Mr. Fish is greeted by Shimmer and tries to ask her out. However, the eel accidentally destroys Mr. Fish's home again, leaving the ending ambiguous but hopeful as he faces another challenge.

Marin disowns Benji because he kidnapped Shimmer in an attempt to use her wish-granting power to keep the cuttlefish in the abyss. When Shimmer reveals she cannot grant wishes, Benji's actions are seen as reckless and harmful, leading Marin to reject him.

According to the rumor, Shimmer can only fulfill one wish every few years. This is why there is a race between Mr. Fish and Benji to reach her first, they both want their wish granted before anyone else claims the single available wish.

After both their homes are destroyed, instead of simply rebuilding, Pip suggests a different approach, visiting Shimmer to find a wish-granting solution. This shifts their goal from fixing their immediate problem to seeking a magical fix.
