lol. everyone seems to know of them, but treat them as a joke. they were already ancient and zooming from planet to planet collection stuff via zero-space when toomin was still toomin the ketran playing his games with his buddies on Ket, way before he became the ellimist.
Even Father, that weird seaweed life form on that moon which toomin was held knew of them and their weird habits, and has captured them and their ships. This was like a million years before the andalites became what they are today. you can piece this together when reading the Ellimist chronicles.
So, why aren't they super advanced yet, or a major galaxy power? lol they've existed as an advanced, space faring race for so long already. K.A was abit unfair to them i reckon. xD
Just for the space faring age of their race alone, they at least deserve some kinda respect.
