Edward is an Emu. He's an Emu at the Zoo. And he's bored with being an Emu. (What do Emus do, anywho?) He overhears visitors at the Zoo extolling the merits of other animals and subsequently decides to become a Seal. Then a Lion. Then a Snake. And, finally, an Emu. And finds he's been replaced. Which is a bit disconcerting. Yet satisfying.
