This is a cartoon I could not find alot of Information about online. My Mum used to watch "Gideon" when she was young, on Yorkshire Television. This is the English Dub of the French cartoon "Gedeon". It ran in the UK from 1979-1985 I will link the wikipedia page below for more info
The show has a rather sinister vibe to it. its hard to describe unless you have watched it yourself, but there are certainly some strange topics for a childrens show. I have found 1 English episode and 2 French episodes on youtube
Gideon and the Ferret: youtu.be/xr48Ow37uto This was re-released on a compilation DVD of old kids shows that my mum bought (Thats how I came to know about the show) Im assuming this is how this episode was found
I hope I can possibly find more episodes of this. Its incredibly wierd and creepy. Finding a number of seasons or list of episodes would be a good start.
