Fred
>Thinks of a plan and tells Shaggy and Scooby to go do stuff to get it ready
Shaggy and Scooby
>Do all the work finding clues and pieces to make a trap for the mystery monster, gives them to Fred because he is the smart one
Velma
>Finds clues in a more psychological way and provides Shaggy and Scooby with snacks, but loses her glasses and becomes retarded
Daphne
>Might be used as bait for the trap, can't remember what else she does
I haven't watched Scooby Doo in decades but I remember them being a pretty well oiled machine.
A well oiled Mystery Machine.
You bitch.
