I am trying to identify a TV show I watched as a child in the UK. It is rather obscure.
The show aired on the ITV network in the late 1970's, I would guess between 1978 to 1973 and definitely shown on a week day afternoon as I recall watching it after school.
It may have been a one off TV special or a very short run of episodes and I only caught the final one because I clearly remember tuning in the follow week and being disappointed it was not being broadcast.
Regarding the show itself, it was a mix of puppets and live action. If memory serves (but it is rather blurry) the main characters were a group of robots or aliens reminiscent of and puppeteered in the same manner as the Smash Martians. For those who don't know, Smash was a brand of instant mashed potatoes and was advertised by puppets meant to be martians. Here is a link to one advert on YouTube. I can be sure it was not simply an advert I watched as it was around 25 minutes long. A fairly standard length for a UK children's TV show.
Plot... I cannot recall many details sadly except that one scene involved the hero group of puppets being caught and imprisoned and another with a character who I think was simply a metallic ball with black eyes glued on teleporting into various places in search of something. At one point it surprises a woman in the bath who throws soap suds at it and screams.
It is possible I am conflating one or two different shows, the Children's Film Foundation film "The Glitterball" may account for some scenes but not all.
