Ken Hunter's Doctor Q and the Jellymen from the Beezer 1966..
The Beezer 15th October 1966.
Heres the sequel to the Jellymen...what was such a horrible creature becomes a helper and friend to the boy.... This also happened to The Goon who became a friend to Popeye and became Alice the Goon wearing a dress and hat.
Still nice drama to see.. I only have the one example so don't know if all the Jellymen are this friendly in this second outing..
