The fairy godfather is based off Vito Corleone from Mario Puzo's "The Godfather," which was adapted into a popular film by Francis Ford Coppola. Marlon Brando played the Godfather and so the fairy godfather's voice and appearance is based off his portrayal in the film.
This was supposed to be part of episode 19 but when I ran out of time last week I had to split the episode in half or risk not getting it out on time. It ended up working out because last week's episode won a trophy on Newgrounds! Both episodes are also roughly the same length and both contain complete scenes so it doesn't seem like one was just chopped from the other.
