Weird planet

When their spaceship crash lands on Earth, Ploo is captured by the Army and taken to the mysterious Area 51. While her brothers, Lek and Klatu, try to rescue her, Ploo uses her ESP to make a new friend.

When siblings Klatu, Lek, and Ploo from the planet Loogl return to the mysterious Area 51 to recover their wrecked spaceship, they meet the Great Ones--four legendary Looglings who crashed in Roswell fifty years earlier.

Siblings Klatu, Lek, and Ploo, along with their human friends Lily and Jo-Jo, travel to Hollywood, California, where the aliens become extras on a science fiction television show while waiting for the spaceship that will take them home.
