Mister F

Mister F is a Letter Boy from The Letter People. He has funny feet (where he gets his sound from), so funny-looking, in fact, that he can never find any shoes that will fit them.

Notable Heroic Role(s)
In "Meet Miss O," during the Catching Game, Mister F takes over for Miss O as Olivia the Ostrich in her Olive Omelette Opera when she has to play the game twice (because she cannot play the ostrich in the opera and the catching game at the same time, as there is only one Miss O). He does this twice when Miss O and Mister T are in the catching and ending clue boxes, respectively, and then, for each time, first, when Mister P is in the starting clue box, and then when Mister H is in it instead.
