Marfalump was a digital character created by Industrial Light & Magic Commercial Productions (ILMCP) in collaboration with BBDO-New York. It was featured in Pepsi commercials promoting Star Wars: Episode I The Phantom Menace.
According to a promotional video released by Pepsi, an employee refers to the origins of Marfalump's name. In the video, the man says "...a lot of people ask me where the name Marfalump came from. But on his planet, that's as common as Smith or Brown here." From this, it's implied that Marfalump is not his first name, but his last.
