Life on planet Jumbadoe had been peaceful for many years. Generations of Monsta lived together happily and care free. There was nothing to worry about. Unfortunately everything was about to change. The Monsta scientists who were working the south end weather station could not believe what they had just witnessed. They ran their data multiple times, but the results were the same over and over again; A meteorite crash was inevitable.

The data suggested that their beloved planet Jumbadoe would not survive. Luckily, years of research had shown that a habitable planet existed not too many light years away and was called "Earth". All Male Monsta got on their rocketships, loaded supplies, loaded Monsta Eggs and left in search of their new home. The journey went well and little problems occurred along the way. When entering Earth’s atmosphere however, the change in air composition caused most of the loading dock doors to fail, scattering Monsta Eggs all over the surface of this new planet. Since haste was required, the Male Monsta decided to leave the Monsta Eggs scattered around the planet. Their first and foremost task was to find a place they and their beloved Female Monsta could escape the doom that waited for them on planet Jumbadoe.
