Sheep (Almost Ghosts)

The sheep was a farm animal that Shaggy Rogers and Scooby-Doo picked up by accident while looking for Dr. Phibes' Cloud Ship.

Season one
They let it ride with them on the mission, and sit in the revamped Mystery Machine to wait for them. While it didn't actually do anything (the autopilot did all the work), it proved useful in intimidating enemies who couldn't believe their eyes when they saw it there.
