A duck once met a porcupine ; they formed a corporation
  Which called itself a Porcuduck ( a beastly conjugation ! ).
  A stork to a turtle said, "Let's put my head upon your torso ;
  We who are so pretty now, as Stortle would be more so !"
  The lizard with the parrot's head thought : taking to the chilli
  After years of eating worms is absolutely silly.
  A prancing goat - one wonders why - was driven by a need
  To bequeath its upper portion ta a crawling centipede.
  The giraffe with grasshopper's limbs reflected : Why should I
  Go for walks in grassy fields, now that I can fly ?
  The nice contented cow will doubtless get a frightful shock
  On finding that its lower lombs belong to a fighting cock.
  It's obvious the Whalephant is not a happy notion :
  The head goes for the jungle, while the tail turns to the ocean,
  The lion's lack of horns distressed him greatly, so
  He teamed up with a dear - now watch his antlers grow !
