cyber chase was great for learning mathematics! - oops, thought you meant the cyber chase series. I have never watched all of the scooby doo shows/movies.
I found it amusing how Velma's outfit didn't really change much, it's the same thing except now it's shorter socks and the clothing is a little darker.
Of course the only thing different with Shaggy and Scooby was the color.
And with Zombie Island, I love how they made the zombies the good guys. I'm tired of seeing zombies as the villains.
Spyridon The Scooby farthest in the picture should have a blue collar.
Though, Scooby never wore a red collar in the older episodes. Because their fashion styles were referencing to older Scooby Doo episodes, whereas Shaggy's came from the 13 Ghosts of Scooby Doo and Fred, Velma, and Daphne's came after that. But I get it, they need to be able to tell the 2 Scoobys apart. Lol.
