The EP, which was initially going to be titled Leftovers, was made available as a mail-in offer for purchasers of the self-titled album Mötley Crüe in a limited quantity of 20,000 copies. The EP features one song from each member of the band ("Planet Boom" by Tommy Lee, "Bittersuite" by Mick Mars, "Father" by Nikki Sixx, and "Friends" by John Corabi), along with the song "Babykills" which is performed by the entire band. It is also the last Mötley Crüe release to feature singer John Corabi.
The rap metal-influenced "Planet Boom" was later released on the soundtrack for Tommy Lee's then-wife Pamela Anderson's movie Barb Wire. However, the song was credited to Tommy Lee only, and the title was changed to "Welcome to Planet Boom". A video was also released for the song around the same time as the movie's release.
