Charlie the Unicorn is a web animation created by Jason Steele, who works at FilmCow. Originally just one video, it was given sequels due to its popularity. Steele also made a parody series of it. It is about the life of Charlie, a lethargic unicorn who is forced to go on a weird adventure with two other unicorns (one blue, one pink, both strange).

When trying to convince Charlie to go with them to the Banana King, the blue and pink unicorns inflate for no apparent reason.
