A suggestion for those going to Uni soon for the first time and worrying about what original thesis they will need to research - seems to me that there is a possible connection between Oodle-Poodle and the Clangers' language. You doubt? Well admitedly as vocalised by the Clangers it may be difficult to discern as the series creators have said that, living in vacuum,
they did not actually communicate by sound, but rather by a type of nuclear magnetic resonance, which was translated to audible whistles for the human audience. It is probably more easily heard in the bass notes of the Soup Dragon - try 7mins into

There is a possible contact at the BBC who may help. He told Postgate "you can’t say that on children’s television, you know, I mean you just can’t.” in the episode where a rocket shoots down the Iron Chicken and Major Clanger kicks a door to make it work and his first words are "oh, s** it, the b***** thing’s stuck again.” (translated from Clanger of course). It was aired anyway.
The series was shown without narration to a group of overseas students, who each felt that the Clangers were speaking their own language.
I think this hints at a root language lost in the mists of time.
Noggin the Nog , in the lands of the North, where the Black Rocks stand guard against the cold sea, in the dark night that is very long the Men of the Northlands sit by their great log fires and they tell a tale...
If we could only find the records of the Concordat of Worms (n.b. It is essential to bear in mind that only dragons may call each other 'worm'. Others do so at their peril.) which was held in the year 984BN (before Nog-time), and resulted in the DRAGONS' FRIENDLY SOCIETY
