Mystery Skulls Animated is a series of official music videos for Mystery Skulls' songs. Alternate terms for it include Mystery Skulls Ghost and MSA. Created by Big Name Fan MysteryBen, the first video follows Vivi, Arthur and their dog Mystery, a trio of paranormal investigators, as they traverse a haunted house and flee from a hostile ghost. The short video and a handful of character profiles provided by MysteryBen quickly developed a thriving fan community, with said video having eight times more views than the original official music video. On the one-year anniversary of the video's release, Mystery Ben announced a plan to create a story arc of about five additional videos starring the same characters seen in Ghost and continue their storyline after the events of the video using other Mystery Skulls songs. On midnight of April 15, 2016, the second music video of that arc was released, "Freaking Out", which introduced a new antagonist and further continued the story of Vivi, Arthur, Mystery, and Lewis after Lewis' death. On June 7th, 2016, the next video, set to the song "Hellbent", was announced to have started storyboarding, and the length of the story was shortened to about five videos.
