Mystery Skulls Animated (MSA) is a series of viral fan-made music videos produced by Ben Mangum (MysteryBen27) featuring the music of the band Mystery Skulls. The series began in 2014 with 'Ghost,' which introduced fans to a Scooby-Doo-inspired trio—Lewis, Vivi, and Arthur—caught in a supernatural mystery that turned tragic. The series became a cornerstone of internet animation culture due to its distinct character designs, vibrant color palette, and compelling hidden lore. Memes often focus on Lewis's dramatic reveal, Arthur’s mechanical arm, or the shocking plot twists that occur during the songs. Its usage spans from simple reaction images to complex 'edit' trends, remaining a staple in the indie animation community.
