Star Street: The Adventures of the Star Kids

Star Street: The Adventures of the Star Kids was a Dutch cartoon from 1991. The show focused on the Star Kids, a number of small pink aliens with appearances and personalities based on the signs of the zodiac. It took place on their home planet, a small, idyllic star-shaped planetoid. The main antagonists were the green blobs, a race of green cowardly aliens living on a neighbouring garbage planet, who were led by the constantly hungry Momo, a large, pink alien warlord.
