'Spooky' originally appeared in the Casper animated cartoons for Famous Paramount Studios. His character then was basically the same as now. Spooky gets into mischief scaring people and animals, while Casper tries to deter him. This of course, makes him want to spook even more. He also appeared in the later "New Casper Cartoon Show" with Casper and Wendy. His first appearance in comics was in "Casper, the Friendly Ghost" #10, in 1953.
