Horace Horsecollar

Horace Horsecollar is a character in the Timeless River. He does not play any essential role other than walking around the Cornerstone Hill with Clarabelle Cow and Clara Cluck. It is assumed that he is still alive and in Disney Castle during Kingdom Hearts II, but Sora never encounters him. In recent scans, Horace makes an appearance in Kingdom Hearts Birth by Sleep in the world Disney Town.

Trivia

 * One of the bonsai figures (the percussionist) in the Courtyard of the Disney Castle bears a striking resemblance to Horace Horsecollar. It could very well be him, as he was the percussionist in The Band Concert.
