My Little Pony: The Mentally Advanced Series is an American abridged animated television series, which was developed in 2011 by Greg of FiMFlamFilosophy. The series of videos recontextualize episodes from the original series, My Little Pony: Friendship is Magic, by re-editing and re-dubbing them.
Eoisode 23 was scheduled to release the day after the channel received the ContentID claim that led to the switch from screencaps to original art. It was only screened at the same con that Episode 11 was showed in (but years later). Unlike Episode 11, it was complete, but the camrip version released by AstrumSpark in April of 2015, lacks the usual rambling end credits and any background music it may have had is not audible.
The episode was never officially released, and instead the whole series was retooled for the negative numbered series.
