There's something very creepy about the Laughing Loony and his ceaseless demonic laugh. It seems he laughs all the time and can't stop. Laughing Loony has auditioned with Snagglefangs. No one knows how he made it. Laughing Loony is one of the most mysterious Sinistras in thumb wrestling. He only appeared on the Sinistras tryouts, sidelines of a match, and in the Season 2 championship where he, Cheeko Rojo and Snagglefangs followed Senator Skull's evil plan to defeat Mr. Extremo. He is not a wrestler.
