Goofy creator (6)
I believe the answer is:
disney
'goofy creator' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for disney that I've seen before include "US cartoon pioneer" , "US film cartoonist" , "Walt, pioneer of cartoon films" , "American film producer, Walter Elias (1901-66)" , "Wealthy (informal)" .)
