Scooby-Doo and the Island Cats

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

Premise
Before leaving 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, they have Shaggy and Scooby stand guard for the black cat creature that’s still around. One hour later, Scooby still keeps guard as Shaggy is asleep. then, Scooby spots 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. Scobey, 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 heads back to the campsite.

At morning, The gang wake up and see a group of cats around their campsite, then the six cats, (the three that went in the cave, and the three that were asleep inside, cut through the crowd. The white one motioned Scooby to look at the horizon, and they see ferries come to the island, and in the ferries, are campers, artists, fishermen, and photographers. The orange cat then motioned the Gang to head for the Mansion, and hide under the floorboards. After a few minutes, They hear some people talking about smuggling the cats out of the island. Scooby goes to take a closer look, but a voice (from when Scooby was in the cavern) said to Scooby not to exit their hiding place, so He stays put.
