Scooby-Doo and the Island Cats

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

Premise
Hours after solving the mystery on their second visit to Moonscar Island, The Mystery Inc. gang learn about the Island Cats' origins, unaware of an evil plot at work...

Synopsis
While Mystery Inc. camp out at Moonscar Island, preparing to leave at morning, they have Shaggy and Scooby stand guard for the black cat creature that’s still around. One hour later, Scooby falls asleep, but wakes up, spotting what He thought was the cat creature, was actually, an orange cat, black cat, and gray cat, all going in the cavern. Scooby wakes Shaggy, and tells Him that He’ll check the cavern. Once inside, He hears voices saying they need a couple more days. Scooby, not sure what the voices were, goes deeper in the caverns and saw only a white cat, brown cat and light brown cat resting on the base of the cat idol. Confused that there was no one else, Scooby was about to exit the cave, until He spots the three cats glowing in a blue color, then leaves quietly but quickly. Scooby, after leaving the cave, spots someone in the shadows exploring the marsh. as Scooby ran back to warn the others, He gets caught in a steel trap, meant for a cat. Two shadows approach the trap Scooby is trapped in. One of the shadows suggests getting rid of the dog by drowning Him. fortunately, before the cage even touched the water, The Cat Creature attacked, and the shadows fled. with the shadows gone, The Cat Creature tore through the cages, freeing the captive cats, but leaves Scooby still inside the cage. Soon, the three cats (Orange, Black, and Gray) help free Scooby from the trap.

At morning, Scooby wakes the gang up and tells them about the shadows, but the gang spot groups of people approaching the island via the ferries, composed of Developers, animal control workers, and photographers. Once the groups arrive, They do some checking, capturing any animals, and photographing the island. All hired by Multi-Millionaire Development Mogul, Mr. P.L. Atinum. Knowing they can’t exit the island without being seen, Scooby and the others, along with the cats, hide in the cavern as as some animal control workers were about to enter, some of the cats’ eyes glow, opening a secret passage to a deeper part, allowing them and Mystery Inc. to follow it, and closes, but not before one of the photographers arrive, witnessing the passage closing. Safe from the interlopers, Mystery Inc. and the cats explore the cavern and at the end of the tunnel, They spot a cat statue, but of a benevolent expression. Six of the cats approach the statue and they glowed a blue color, then fell asleep. after a few moments, The six cats get up on their hind legs as one of them, a white cat (named Thalaj) explained to Mystery Inc. through telepathy, that when any humans with ill intent to exploit or mistreat them, the cats would find ways to drive the bad humans away.once out of the cavern, leading to the island’s southernmost point, the black cat creature went to attack Mystery Inc. but the six cats jumped in front, calming the cat creature down, and leave them in peace,
