Funny you should quote that poem, as I just yesterday read the Ursula K LeGuin story named after it.

Anyway we need some Silver BLOBs here! And here they are!

• A punny BLOB to Neil D for the inarguable:
  Bears usually don't eat
  Tough collie meat
  This bear was just an old meany
• A Merseyside BLOB to Ceto for the demiursine:
  Suddenly
  I'm not half the bear I used to be
• A hey-nonny BLOB to Matthew Edwards for the eyebrow-raising:
  At the sight of the collie his passion grew harder.
• And finally, a whiff of Matthew's BLOB to Georgiansilver

Keep up the great work, Challengees!
