Mrs Coot is a female anthropomorphic parrot.
Description
This parrot woman married Mr Coot, son of Casey Coot, and together they had two sons, Marmaduke and Botcho. Judging from how both turned out to be kooky inventors, it is probable that either Mrs Coot or her husband had at least some interest in gadgeteering.
Behind the scenes
Mrs Coot never appeared in a story; her existence can only be inferred from his two sons'.
