FRODO: Mix grub with radishes, at first, and see him emerge.
L
EGOLAS: The French aims, if confusing, reveal him.
LOCKBEARER: The floor of my grandfather’s house, if initially lost, reveals him. (Sing it!)
O
LORIN: Toilet edge with a nasal change. A slight flush at the beginning will reveal him.
B
OROMIR: Troubled Plantagenet, I recalled, at first, but a king-in-waiting? Hmmm ….
WINGFOOT: He’s defined by two appendages.
SAMWISE: He swam around, although this is against his nature, (that is, swallowing seaweed initially).
HOLDWINE: He can take his drink.
B
ILL: Invoice him.
PIPPIN: A thing unfairly sold, twice? Second lost; direction gained. See him.
Indeed. The floor was a CLOCK-BEARER ... lose the initial letter and you get ... GIMLI the LOCKBEARER.
