Does anyone remember a little cartoon in the 1970's, in which the main character was a egg-like crystal(?) creature named Ludwig? When it came on, Ludwig would fly into the scene with a little propeller, to the tune of a little violin musical ditty (Beethoven, I assume)
When landing, Ludwig would produce arms, legs, a violin and bow out of his panels, and begin playing. Also, a guy with a Sherlock Holmes hat and cape would always look on with binoculars. He'd say bemusedly, "ah.....Ludwig!" The show always came on this way.
Very, very few people remember this. I'd like to know if anyone here does. (Also, hopefully to verify that I am not insane)
