In 1975, Kenner produced a doll that was the brain child of special effects artist/director/writer Alan Ormsby who acted and did the makeup for the film "Children Shouldn't Play with Dead Things" and authored the classic scolastic book Movie Monsters which probably spawned a legion of Monster kids by itself.
Hugo was a great concept, a puppet version of Lon Chaney sr, complete with makeup kit so you could give him hundreds of combinations of disguises. As a bonus (?) the Hugo puppet on it's own was creepier than ten ventriloquist dummies, his unusual stare had him featured in Pee Wee Herman's original act and on the popular "Uncle Floyd Show".
