Miss A

Miss A is a Letter Girl from The Letter People. She is the first Letter Girl/Vowel to appear on the show, and the only one whose debut episode does not have the Catching Game. At first, she is the only Letter Girl, which meant that until another Letter Girl arrived in Letter People Land, she had to be in every word in the Catching Game, explaining why the Catching Clue Box is bigger than the Starting and Ending ones.

Miss A gets her first (and at first, only) sound from the same sound that starts "Achoo!" (with the "A" being pronounced as in "apple," "tax," and "pass"), for she sneezes when something makes her happy, much to the idea that Dr. Alice Antler would think she was sick and attempt, in vain, to cure her.

Miss A's notable hero role is assisting Poopsie Van Snert with simply-spelled words whose meanings he did not know with certain other letter people, such as being silent and between the Catching and Ending Clue Boxes in "boat" and "steam," but being in the Catching Clue Box in "pail," to help him and Nardo with the former's problem on his own birthday.

Additionally, Miss A also assisted Mister C and Mister K with their problem about when Mister C (who gets his sound from the same sound that starts "Cotton Candy") and/or Mister K (whose is from "Kicking") should use their sounds before which vowel, and helps to decide which of them should start or end a squoosh (so that Mister K can be in a squoosh without kicking another person).
