It was revealed at episode's end that the group's manager, Roger, was Mamba Wamba, and Lila was an evil co-conspirator in his scheme. Knowing that Mamba Wamba would be a hit song, Roger and Lila attempted to cheat the rest of the band out of their money, using the Mamba Wamba legend to trick the group into signing away their rights to the song. In fact, the parchment was actually a legal release, as Velma removed the parchment covering to reveal the release. Lila was arrested for her villainous role.
Lila resurfaced in the 2014 film, Scooby-Doo! Frankencreepy, aligning with past Scooby Doo villains Cuthbert Crawls, C.L. Magnus, and Mama Mione to get their revenge on Mystery Inc. She disguised herself as a gypsy merchant, and used an inflatable dress to make Daphne believe she was unattractive. Lila and the rest ot the group were caught by the group, and she was again arrested.
