Sir Oswald (also known as Sir Oswald the Merciless) is a knight who engaged Sooty in a duel. He was encased in jelly from Sooty's magic spell. Then he was set free when the jelly completely melts. He then attempts to capture the gang when they want to go back to their own time, but he falls into the wishing well and gets trapped inside it. He is voiced by Jimmy Hibbert.
