C.K. is T.D. Kennelly's uncle who works on a farm.
His pets include sheep, cows, and chickens.
His interests include fishing, sandwiches and farming. He's very patient and also a morning person.
He looks like a lanky adult version of T.D.
- He was the reason T.D.'s codeword for sandwich/sandwiches was "frog slime". Before he and T.D. had some memorably delicious sandwiches, T.D. had his first swim in the river and thought the silt was frog slime.
