This Idea takes place, right after Scooby-Doo Return to Zombie Island.

Premise
While on Moonscar Island, Scooby-Doo has an adventure with the Cats there, and also learn about the Island Cats' origins, unaware of an evil plot at work...

Synopsis
On Moonscar Island, a day after Moonscar's Treasure is found, the rest of Mystery Inc. stay to check for potential dangers, placing Danger signs on potential hazards, along with a "Do Not Enter" sign at the cavern containing the cat idol. Inside Moonscar Mansion, as the gang is ready to rest, Shaggy accidentally broke a floorboard, and found a few notebooks, one in particular, is the history of cats, from Ancient Greece to the 21st century. 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. After Scooby noticed that the cats were following Him, He goes faster, Then, while running to get away from the cats, 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 frees 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, as one cat, A gray-furred cat named Zanadu, led Scooby in the cave, and has Him imagine they are in the Louisiana marshes. Where six stray cats are exploring Louisiana for a place to call home. They never found one as they stayed at a dock. Then, the the illusion ended afterward.

Back in reality, knowing that the two figures would come back, the Cats go back into hiding, except for a semi-hairless one, who is sick, as Scooby warns Shaggy and the others about the cloaked beings. At morning, as the gang checked the Entire island for clues, a group of Land Developers led by Mr. P. L. Atinum came to the island to check the environment and check if it can be turned into a residential/commercial area. After that, a brown cat named Bunna, Zanadu's mate, placed Her paw on Scooby, bringing His mind to where Zanadu left off. Days later, after being forced to hunt down rats, mice, and stealing food in the alleys, the six cats were picked up by three people and to be taken to an island, once there, they were celebrated by the villagers there, with that, the cats decided to make the island their home as the illusion ended. soon, one of the developers spot some cats living there, including some rare breeds and the sick cat. But, as He called for the animal shelter, The Black Cat Creature (from the sequel) appears, destroys the phone, and scares away the worker, who calls for the animal shelter with another worker’s cell phone.

Afterward, a blue cat named Azrak, places Her paw on a sleeping Scooby, warping Him in the time, right after Captain Morgan Moonscar made the settlers march to an alligator deaths, as the six cats follow the survivors Simone and Lena to a cave, once inside, they see two Were-cats and they run away, as the two Were-Cats attack Moonscar and His crew. After the pirates were drained, the two settlers return to being human, only until the next harvest moon. realizing this, the Cats hide in the cave from the two settlers they thought were good people. the illusion ended, as a Group of straycatchers arrive, coming to capture any stray cats in the area. Scooby, thinking about the what could happen to the cats without licenses, create makeshift collars with Daphne's help, but, with only enough time to make six. Eventually, one of the cloaked beings capture Scooby, and try to take Him away, but one cat attacked the being, causing Him to trip into a sinkhole. The being calls for help, as Azrak helped free Scooby. the cloaked being called for 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 named Tuqaliu, who is Azrak's mate, places His paw on Scooby, and tells Him that while hiding, they look at the idol, after a few seconds, a strange power goes into the six cats who were given immortality and telepathy. with that the six cats decided to make it a mission to end the were-cat era as they prepare for the future.

Soon, one cloaked being infiltrated 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. However, the fog causes Him to fall asleep, as well. Hours later, morning came, with Scooby waking up to find the place empty. meaning Shaggy and the others along with almost all of the cats are gone! Scooby then spots the catnappers going on a raft, with the captives forced to board. Fortunately, the cat creature attacks the catnappers, But, is caught in a cage as the catnappers take the cat idol as well, to be auctioned off. The rest of Mystery Inc. is captured by a few of the catnappers' henchmen and they leave the island undetected. In despair, Scooby wanders the island and encounters the six aging cats (Who were hiding in the forest) and explained to them that Mystery Inc and the rest of the cats were captured along with the cat idol. The cats after hearing this, after learning 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 the six aging cats row to the mainland.

As night was nearing, Scooby and the Cats reach the mainland, the black cat named Aswad places His paw on Scooby. One year, after the settlers became were-cats, The Six Cats with their kittens were told telepathically by the idol, that as long as they were within the range of the idol, The six cats would keep their immortality, and they decide to wait for a cat not from the island to warn people of the Were-Cats as they kept watch as the kittens, once old enough, could leave the island in hopes of getting help. but, with only humans coming to the island, the Cats had no luck, as the six cats for over 200 years waited, as they continued to have kittens, hoping that They would bring someone to defeat the Were-Cats. the illusion ended after that as Scooby and the cats search for the catnappers' whereabouts.

Meanwhile, While imprisoned in the black cloaked beings' hideout, Mystery Inc. sees one catnapper take 16 cages, each one containing a cat, to an empty van, as a person in a trench jacket, gives money to the catnappers. Soon, Scooby 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 the six cats back to the island. The culprits as it turned out were the two of the Animal Shelter workers, who are in fact, Erwin and Edwin, whom Mr. Atinum recognized as workers He fired two years ago, because the two had falsified records, just to get a job. Erwin and Edwin, 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. With the criminals arrested, Scooby and the gang offer to take the kidnapped cats and the idol back to Moonscar Island, on the ferry which they all board.

After arriving back, the gang put the idol back to its pedestal, with that, the six cats regained their youth, as a white cat named Abyad, Aswad's Mate, placed Her paw on Scooby, at the time of right before Mystery Inc. arrived, Two Cats, (Both Lykoi) arrived, a couple days later, After learning that the Lykoi Cats' owners were drained of their life force, the male Lykoi, whose rage triggered the idol to give the cat a humanoid form, to get His revenge on the Were-Cats, but was no match and was forced to retreat. the illusion ended, as the Cat Creature went to the shrine and after a few seconds, He returned to being a normal Lykoi-breed cat named Dhiib, who learned from the other cats, that His owners' deathes were avenged, thanks to Scooby and His friends, then the sick cat from earlier tended to an unconscious Dhiib. Mr. Atinum, realizing that the island is best left to the cats, decided to leave the island as is. as the Gang was ready to head for home, the six cats put their paws on Scooby, and He sees a vision of the future, where cats and dogs are living together in peace, making Scooby going “Scooby-Dooby-Doo!” As the cats meow in victory.
