There are human skulls everywhere on the Mixel Moon. heck, Kraw literaly holds one in Vaudeville Fun! Maybe all the humans got killed by the Mixels and the world became some sort of radioactive planet?

Wait, what if the Nixels are evolved humans? What if Mixels takes place many eons after the apocalypse, although there are still survivors?
