The alligators have brown scales, orange stomachs, and yellow sclera.
They are very dangerous and blood-thirsty.
Scooby-Doo On Zombie Island
Fred Jones, Daphne Blake, and Velma Dinkley told Jacques to turn the boat, but he wasn't able to fast enough. Velma then threw a life preserver to them, but the alligators ate it, and continued after Shaggy and Scooby. Just then, Snakebite Scruggs appeared on his boat, with a sharp long hook, at first looking like he was going to hurt Shaggy and Scooby, but instead he caught the alligators with it, and tussled with them, allowing Shaggy and Scooby to get safely aboard his boat. Shaggy thanked him, but his act of kindness was embittered by the fact they scared off his sought after catch: Big Mona.
Later at night, while Scooby and Shaggy were running away from zombies, they jumped across platforms on a river, mistaking an alligator for one.
