Fredegar Bolger
Fredegar "Fatty" Bolger, a
Hobbit in
J. R. R. Tolkien's fantasy novel
The Lord of the Rings, knew that
Frodo had the
Ring. He stayed behind in an attempt to keep up appearances while Frodo,
Sam,
Merry and
Pippin braved the dark forest east of the Brandywine on their way to
Rivendell. He was frightened half out of his wits by the arrival of the
Nazgûl but escaped unharmed.
Warning: wikipedia contains spoilers
During Saruman's rule of the Shire he was imprisoned and starved, so that after his release nobody could call him Fatty any more.
