Mr. Tiddlywinks, played by Bill, is LoadingReadyRun's own horror movie villain. Although Mr. Tiddlywinks is first named in Ways to Get Yourself Killed in a Horror Movie he makes an appearance in Ways to Make Someone Leave a Room armed with a machete rather than a meat cleaver as in later videos. He appears also in The LoadingReadyRumble, Moving Out, both with his meat cleaver, and 'Movie' Movies Movie armed with what the crew describes as an "Orc sword" . The crew theorizes that whenever Mr. Tiddlywinks kills somebody with a weapon, he exchanges his weapon for theirs.
Mr. Tiddlywinks can be summoned by saying his name three times, and is a big fan of Star Trek.
