## Summary

The episode opens with Fishtronaut, Marina, and Zeek who have presents that are for a stingray's birthday party (the stingray is also a friend of the trio) and Rosy and her friends started appearing in which Rosy says that the stingray's party started already. Marina and Fishtronaut decide to dive underwater for the stingray's party. Underwater, the trio, Rosy, and her friends meet the manta ray who couldn't find any friends for her party. Back at Cicada Beach, Zeek finds a jump rope washed up ashore and is suddenly washed up by an incoming wave. Zeek thinks that he is drowning, but a sand crab appears and says that he never saw someone drowning in the sand. It is revealed that there is so much trash in the beach.

Back underwater, the stingray reveals her memories of her past birthday parties that used to be fun with many creatures, but this party, her friends keep on disappearing, leaving the ray worried and is unable to find any sea creature. Back to Zeek who is cleaning up the beach, a P.O.P. arrives towards the trio.

**P.O.P. Clues:** a hose and a blank portrait

Receiving the clues, Fishtronaut says that the clues aren't the manta's present, but they may have something to do with their friend the stingray. Fishtronaut and Marina then decide to go back to the spot where the stingray is feeling sad. Underwater, the seafloor is completely deserted with trash, as explained by Rosy. Fishtronaut, Marina, and Rosy encounter two fish who must move, since there are no nutritious food for them. One of them says that they used to eat algae by the coral reef, but the reef has no algae, due to the trash on the seafloor causing pollution. Above surface, Zeek asks Fishtronaut, Marina, and Rosy if they need any help, but Fishtronaut tells him that there is no need to shout at them.

Suddenly, the coral reef where the fish used to eat algae is polluted with trash. Fishtronaut does a plan to clean up the sick coral reef with the help of Marina, Rosy, and her three friends. Having removed the trash on the coral reef, Fishtronaut arrives to the spot where Zeek is on an inflatable raft and Zeek tosses a bottle in the trash bag. Fishtronaut was able to convert the trash into a cube by using one of his gadgets that help convert the trash into a garbage cube and dispose it in a recycling bin. Rosy then talks to Zeek that she and the gang took care of the sick reef, but something is still not right: she started thinking of a plan to restore marine life on the coral reef. Zeek then tries to make a plan to take a piece of coral back to Dr. Green, but Fishtronaut says that corals are actually living beings. Marina found out that the hose is linked to the other one used by Dr. Green at the plant nursery at the Beanstalk Care Center.

The trio arrives at Dr. Green's nursery, in which Marina tells him that the seafloor near the stingray's home has actually become an underwater desert (this pollution causes a lack of coral, algae, food, and thus reduces the fish population). Dr. Green is also worried that species cannot survive without coral in the seafloor. While Rosy talks to Dr. Green about the importance of animals eating algae, she tells her friends to stop making noises while she's talking to Dr. Green. Dr. Green explains the evolution of corals as Marina learned in school that polyps look like plants, but are actually little animals protected by a shell that is hard as a bone and Dr. Green explains that polyps grow together, forming large colonies called coral reefs and coral reefs cannot survive when the water is dirty. Dr. Green says that corals can be restored by raising baby polyps in an underwater nursery and then put them on the reef. The trio and Dr. Green began raising baby polyps until they are ready to be brought back to the sick coral reef. Later on, the coral reef starts feeling better, bringing back the underwater population. The stingray and Rosy are happy for restoring the coral reef back to life. All of a sudden, another P.O.P. arrives towards the trio.

**P.O.P. Rewards:** a puzzle coral reef

Receiving the reward, the trio decides to use puzzle pieces to make an image of a beautiful coral reef.
