Surely, as someone lucky enough to live in the States, you have easy access to old Donald Duck comics? Was about 1942 the great Carl Barks wrote/illustrated the excellent Donald Duck comic story called The Pixilated Parrot. I could only get a Gladstone reprint in 1989. Note, pixilated, not pixelated. Pixilated means annoyingly crazy/naughty, and also blotto drunko.
