PRY
FTAN:  Initially Frodo’s pantry, but now in chaos for this beast!
2.  Running flush – that’s him!
BING
O:  He uncoils for a springy sound.  Not much, though.
4.  No party for him?
BLAD
ORTHIN:  He renders Thora blind, and Thorin bald!
THEME:  FORMER NAMES OF CHARACTERS IN EARLY DRAFTS:
Smaug was Pryftan
Frodo was Bingo
Gandalf was Bladorthin
HS, how can it be just The Hobbit when the first clue guessed was a prototype for a LOTR character?  
 
Good work on Bladorthin and Pryftan, though!  (And Nerwen on Boing).
