Dreamfinder
The star of the original version of the Disney ride, Journey Into Imagination. He's an old, jolly man who rides a blimp with no interior and sings with his imaginary dragon, Figment, but everyone wants him back anyway because Eric Idle/Nigel Channing makes for a terrifying moon. He's most often remembered in the Dreamcatcher/Dream Machine/blimp.
Dreamfinder: "Two tiny wings, eyes big and yellow. Horn of a steer, but a lovable fellow! From head to tail, he's royal purple pigment,and there, viola!, you've got a Figment!"
