From the box:
Hilarious invasion from four extraordinary aliens.
The hilarious adventures of four ordinary aliens who crash land on Earth may give new dimension to the word “Moron.”
The aliens are quite human, and entirely uncurious about Earth and what they find there. Conversely, Earthling interest in them is so intense that they soon become international celebrities and pop superstars.
This could just be the beginning for the Morons From Outer Space.
