Lonely little pony

On the way to Napton this pony stood forlornly on the towpath. How did he get there and where is his owner? A lady was walking her dog toward the pony and I enquired if she knew to whom it belonged. Unfortunately she was also off a boat further round but she did say that a splash was heard from the other bank late last night and could only assume it had fallen in and somehow managed to get himself out towpath side. Not a lot we could do so we continued on our way.
