Some other frequent characters in this strip are
Howland Owl (usually called Howlan' Owl), the bookish, blustering blowhard;
Porky Pine, the continually glum-seeming porcupine (who has offered to smile on many a Christmas---but somehow, the light always goes out just when he does so);
and Seminole Sam, the double-dealing fox.
Even Walt Kelly had earlier comic strip artists to look up to and emulate.
Indeed, in the 1950s he included as one of the stories in "Pogo" an homage to Krazy Kat.
