Casper (Julie McWhirter) and Hairy Scarey (John Stephenson) accompany Minnie & Maxie to a Old West style space colony overrun by ghosts. While Hairy's hoping to find some old friends, if you will, he might as well keep on hoping while "Casper Ghosts West":
You know, if I didn't know any better, I'd think the part of Hairy may've been originally meant for Paul Winchell. You can picture him using Fleegle's voice (later recycled for a Scrubbing Bubble), especially that distinctive laugh, can't you?
Not so sure if Laurel Page (Minnie) did any more work after Casper & The Angels was cancelled. She got 2 years out of Captain Caveman, but was hardly heard from during the 80's, unless some of you can fill the blanks.
