Mister K

Mister K is a Letter Person from The Letter People. He has the same starting sound that starts "Kicking," much to the initial dismay of Mister C because his sound is the same sound that starts "Cotton Candy," all of which start with the same sound. He is a big kicker, but he likes it so much he doesn't remember when to stop, but he has no intention of kicking anyone alive.

In his debut episode "Meet Mister K," he takes on the hero role, as when the Grand Shish of Kebab sends him a telegram, he helps her rescue her father the King. He picks one of four keys (three of which have a capital K on it, and one of which has a lowercase one), and because one has a lowercase K, he picks it and tries it out, and unlocks the door that the King is confined to. Mister K declines any reward for his kindness because his sound is enough.
