For the real reason for "Why the Platypus"
You need to read Terry Pratchett's "The Last Continent"!
And JayT, I believe that some of the Sheep, could be considered normal (Harmless) Animals!
Interesting Platypus trivia, Did you know that the Venom from the Male Platypus, specifically targets mammalian pain receptor cells?
(To be more accurate, its primary target is platypus pain receptor cells.)
Being stung by a male Platypus, is one of the more painfull events you can ever experience, and as an aside, All Opiates (Heroin, morphine, etc..), or any other regular analgesics, such as asprin, are ineffective at blocking this pain.
Oh, And I have often seen platypus in the wild, so I personally know, that they are a real animal!
