The Return of the Son of Monster Magnet

It is the longest song on the album, at 12:17, consisting of 2 parts: "Ritual Dance Of The Child-Killer", and "Nullis Pretii (No Commercial Potential)".

The name of the song was probably inspired by a toy called "Monster Magnet" from the Wham-O company which was then being heavily advertised on American television.

Apparently for budgetary reasons, Verve executives curtailed further recording of the track even after shelling out $500[5] for rented percussion.

Unlike many of his extended works, Zappa never augmented or completed this piece when he had the time, money and his own recording studio.

According to Beatles author and Zappa biographer Barry Miles, the unreleased Beatles experimental track "Carnival of Light" which was recorded in January 1967 resembles "The Return of The Son of Monster Magnet", although it is believed that "Carnival of Light" is more fragmented and abstract than Zappa's effort the previous year.
