The Polyglobs are a sapient species of globular entities who are glowing translucent rainbow in color, and have to ability to shapeshift. The concept of identity is alien to them, as they shapeshift from one form to another to avoid predators. They were encountered by human explorers on the planet Muraldoron 6 in the binary star system of Muraldoron. The humans later learned that the Polyglobs weren't native to the planet but were just explorers themselves as a matter of fact. This was in the story called "The One with No Identity".
