The whole universe worships the Little Prince, but no one pays any attention to his cousin, Fat Princess Petronia. In contrast she's sullen and completely unsentimental. She just doesn't fit the princess cliche at all: She hates pink frills and loves maths. Naturally, the Little Prince has a huge planet while Petronia is stuck on probably the tiniest and most boring planet in the whole wide universe. With the help of multi-purpose worm Mirco, she tries to pep up her dismal life by travelling the cosmos by wormhole or by attempting to meet David Bowie - usually without success.
