Premise
Returning to Moonscar Island, The Scooby-Doo gang along with Josie and the Pussycats have an adventure with the Cats there, and also learn about the Island Cats' origins, unaware of an evil plot at work...

Synopsis
On a visit to New Orleans, Mystery Inc has just busted a criminal smuggling printing plates in giant masks. As the police took the criminal to jail, The gang saw a sign saying, "Island Property for sale. Residential/Commercial. Potential buyers only!" As the gang head to their Van, they spot a young boy holding a bindle, sneaking on a boat. The gang went after him, until they realize, that the boat they're on, casts off.

Minutes later, the gang catch up to the boy, and realize that the boy ran away from home. The gang, mostly Shaggy, tell the boy, Whose name is Erwin, that running away from home isn't a good idea. Erwin explained that He doesn't want to return home, so the gang decide to take a little more time to convince Him. On the way, The gang meet Josie and the Pussycats, who came to a benefit concert. Arriving at where the boat docks, the gang learn that the property is Moonscar Island. Once there, they see a group of workers running away hopping the boat for the mainland, due to a roaring being, separating Sebastian from the Josie group, who are still on the boat. On the way to Moonscar Mansion, they and Erwin, encounter three potential buyers, composed of Joseph, a quirky artist, Celeste, a florist from the mainland with Sorrow, Her female Scottish Fold cat, and Melissa, an animal activist.

Noticing that there are no cats to be seen in the marshes, the gang go inside Moonscar Mansion, and spot six cats there (The same six cats that dug Moonscar's treasure). Of course, Sebastian observed the six, and meowed some questions. Then, Shaggy accidentally broke a floorboard, and under it, they find a few notebooks. but what was really interesting was the words on the floorboard, in unusual characters. Edwin recognizes it as Egyptian letters, which is "Bunna". The gang read the details, as Scooby wonders about the unusual writing. At nighttime, Scooby-Doo is looking up at the night sky, wandering the island, unknowingly followed by a few cats who go after the great dane. After Scooby noticed that the cats were following Him, He goes faster, Then, while running to get away, He accidentally bumps into two silhouetted figures wearing Black cloaks, who were putting some cats in cages as one enters the cave. The two figures fled after being spotted, as Scooby cautiously freed the caged cats, including the beige kitten who startled Him in the previous incident, thinking that He’d be attacked. But the cats purred around the bewildered Great Dane.

Returning to the mansion with the cats, the Six cats come out of their hiding places, as a brown one approaches Scooby and nuzzles the word "Bunna", on the broken floorboard, then approaches Edwin who softly scratches the cat's head. Scooby asks if Bunna was His name, which the cat nodded as Edwin says Bunna is a girl. Then, as the gang was asleep, Scooby dreamed that He and a group of cats are running from a mob of hunters, but escaped with their lives. After waking up, Scooby, knowing that the two figures would come back, tells the others about the cloaked beings, and suggests not telling Erwin. At morning, as the gang and Sebastian checked the Entire island for clues, another potential buyer, and farm mogul, Mr. P. L. Atinum arrives at the island, looking to turn the island into a place for gardeners to live and work.

As Scooby watched what’s going on, He, Shaggy, and Sebastian hear a scratching sound and they see a light brown cat there, scratching on a dead tree, which Melissa recognizes, is Chinese for “Zong-se”. Scooby asked if Zong-se is the name of the cat that carved on the tree, the light-brown cat nodded, then ran off to avoid being seen by the other humans.

While Mystery Inc. continue checking for clues, they, without being seen, see Joseph with Notepads as Celeste takes pictures of the felines. thinking the two are up to something, The gang go to check as a gray cat climbs on Scooby’s back. At a beach, the gray cat gets off and leads the gang to a boulder, which says "Iiath" in an irish language, and She hides in an old tree alongside Zong-se, who is His mate. soon, a group of straycatchers arrive, coming to capture any stray cats in the area. Melissa tells the stray catchers to leave since visiting the island is only for potential buyers. They also see Celeste check the island for rare flowers.

At sundown, One of the cloaked beings capture Scooby, and try to take Him away, but Sebastian attacked the being, causing Him to trip into a sinkhole. The being calls for help, as the other to help Him get out seconds before the developers arrived. Later, at night, Scooby sees an animal shelter worker exploring and search for any cats hiding in the island. Scooby then goes to the mansion, and quietly sees the cats hiding inside. Then, an Orange cat leads Scooby to the garage, where He spots more egyptian characters, as the orange cat claws the word, meaning “Tuqaliu”. then the cat leaves as Scooby asks if Tuqaliu is Bunna's mate. The orange cat nodded and went off.

Seconds later, a cloaked being infiltrates the mansion as violet fog goes inside and quietly captures the cats one by one. Scooby sneaks off to warn the gang about the catnapper as Sebastian runs to a hiding place. However, the fog cause both of them to fall asleep, as well. At dawn, Scooby wakes up to find the place empty. Scooby then spots the cloaked catnappers going on a black submarine, with hundreds of cats in cages. Then a cat creature (from the previous incident) attacks the catnappers, But, is caught in a cage as the catnappers take the cat idol from the cavern as well, to be auctioned off.

Scooby goes to warn the rest of Mystery Inc. but they are captured, as well. In despair, Scooby wanders the island and encounter Sebastian and the six cats (Who began to age) and Erwin, who explained to them that Mystery Inc. and the rest of the cats were captured along with the cat idol. The cats after hearing this, try to find a way to bring the idol back, and they use a big wood board as a makeshift boat. Scooby along with Edwin, Sebastian, and the six aging cats row to the mainland.

As night was nearing, Erwin explained to Scooby that the reason, He ran away from home was that after His Mother passed away, His elder brother bullied Erwin and treated him like a criminal. So, a few weeks after suffering such treatment, Erwin ran away to get back at his brother, before Scooby and the others reach the mainland, Scooby says that He'll help Erwin someway. Arriving at the mainland, the black cat leads Scooby and Edwin to a dilapidated pier, and on a board, Edwin read it as the greek word, "Mavro". the group then search for the catnappers' whereabouts as Edwin and the white cat go to tell the police. Meanwhile, While imprisoned in the black cloaked beings' hideout, Mystery Inc. sees one catnapper bring an idol and the cats in cages as a person in a trench jacket, gives money to the catnappers. Soon, Scooby, Sebastian, and the six cats who are now elderly, bust in and free the hostages, along with the cat creature, after being freed, chase the culprits, scaring them into the hands of the police, who arrest them and the buyer, as the Cat Creature takes Sebastian, the six cats and Erwin back to the island.

The culprits as it turned out were the two of the Animal Shelter workers, who are in fact, John and Joan, whom Mr. Atinum recognized as workers He fired two years ago, because the two had falsified records, just to get a job. The two workers, seeking revenge, became Co-leaders of a cat trafficking group, known for smuggling cats from all over the world, selling rare-breed ones to the highest bidder, and planting the other cats in businesses, so that the Health Department would shut down the businesses, so John and Joan could buy them at cheaper prices. Joseph, who is in fact, an undercover agent for ASPCA, arrests the thieves, as Melissa starts to become interested in Him. Scooby and the gang offer to take the kidnapped cats and the idol back to Moonscar Island, on the ferry which they all board, including Mr. Atinum, when the gang said Erwin's name.

After arriving back, the gang put the idol back to its pedestal, with that, the six cats regained their youth, as a white cat showed a word in Egyptian on the idol, which Edwin analyzed, "Abyad". Edwin, after realizing that the six words were the names of colors, places the six cats in position, and like magic, the cats levitate with their eyes glowing and explainthrough Sebastian, that the six cats were once mortal cats trying to escape the cruelty of the Salem Witch Trials, headed for a safe place, and after swimming to an island, they made it their home. The cats Had many kittens and lived in peace. Years later, a group of people visit the island, and made it their home. the people then sculpted a cat Idol, said to protect the island’s denizens and cats. At midnight, the six cats who were about to die from old age, slept near it, and like magic, the cats became young again at dawn. the humans were not aware of that power. But, decades later, Morgan Moonscar attacks the island and unintentionally started the terror of the were-cats. The cats who saw the tragedy, decided to band together to warn people from the mainland about the terror of the Were-Cats, but the six cats couldn’t leave the island since they could lose their immortality if they were out of the idol’s range, or if the idol was removed from the pedestal. until the day Mystery Inc. came to Moonscar Island they had little to no luck warning the victims to be. but, Since the were-cats’ demise, the cats were living peacefully again as the illusion ended.

As for the cat creature, The gang spot him asleep. the cats explained through telekinesis, that the cat creature was once a normal cat, who traveled to the island to find His owners, who were last seen on the island. realizing the Cat's owner died at the hands of the were-cats, the Cat's grief activates the idol, causing the cat to have a humanoid form, but robbed Him of His sanity, then, Celeste‘s cat came in the cave nuzzling the creature, turning him back to a cat, seconds before Celeste came in. Celeste offers the cat a place to call home. the Cat and Sorrow jumps in Celeste’s arms, as she names Him Wolf Eye.

As the gang exit the cave, they see the island beautiful, thanks to the idol's magic. Mr. Atinum, after reconciling with Erwin, who is Mr. Atinum's missing son. Mr. Atinum said to his son, that He'll help put a stop to the bullying Erwin suffered at the hands of his brother and declared that the island will be left alone as is as Josie's gang return to pick up Sebastian. The next day, Josie and Her group, perform a concert, on the island to help the cats have homes, as Sebastian is lovingly pursued by a white cat. As for the Scooby Gang, they applaud as the six cats look into the future, seeing peace between cats and dogs.
