Australian Creatures: Lesson #3 is an unofficial parodical comic strip created by Don Rosa prior to becoming an official Disney creator. It features Fethry Duck.
Plot[]
A lesson about Australian wildlife surprisingly covers more than one "odd duck-billed creature": Ornythorynchus Anatinus, the Duck-Billed Platypus, is joined by… Fethry Duck, the Duck-Billed Duck!
Behind the scenes[]
First printed in The Rocket's Blast Comic Collector #125, without Disney's approval, in 1974, this comic strip was also printed under an official Disney license in the Norwegian, German, Swedish, Finnish and Danish Don Rosa Libraries.
Predating his more serious Duckverse work, this is also one of the few instances of Don Rosa using the character of Fethry Duck.
