It's
Daffy Duck (not Duffy Duck
s) and
Donald Duck (not Ronald Duck
s).
Daffy Duck (along with Bugs Bunny and all their pals) are from the cartoon shop Looney Toons, from Warner Bros.
This is not a part of Disney. In fact, Warner Bros. introduced some cartoons in the early 1930's, hoping to beat Disney's studio in popularity. They were competitors.
Donald Duck (along with Mickey Mouse, Goofy, and all their pals) is from Disney, yes.
Just had to set the record straight. "Aw, phooey!"
