The Floxy Theater is an old theater. It appears in the episode Menace, Maestro Please of the 1987 TMNT cartoon. Over the years it had been abandoned and become dilapidated, but was scheduled to be renovated into a new wave dance club.
The Floxy was said to be haunted by a Phantom who did not wish for the renovations to take place. This Phantom turned out to be an alien by the name of Erk, who had become trapped on Earth and whose damaged ship was integrally placed in the Floxy as a pipe organ.
