Cosgrove Hall was a production company which was a hero of mine during childhood (they made all the best British shows - such as "Danger Mouse", "The Wind In The Willows", "Alias The Jester", "Avenger Penguins" and "Victor And Hugo").
I was a very young kid when "Count Duckula" aired for the first time, but since that time, this show has become a very fond memory of mine.
Count Duckula is about a vampire duck (who actually didn't drink blood - but instead was a vegetarian). The reason he was a vegetarian was because during his resurrection process the ingredients in bringing him back to life were mixed up (instead of blood, tomato sauce was used).
Duckula is assisted by two servants, Igor (a character who is always trying to revert Duckula back to his evil ways) and Nanny (a bumbling over-sized hen, who is very protective of her little "Ducky-boos").
This is classic British animation - one of my very favourite childhood shows. I will always love this one!
