So this is some thoughts of the show which i think might make sense but hey, im new here so here we go: HUMANS ARE EXTINCT!, so yeah i feel like the little creatures who are not humans in my case ( ill just call em cpu's ) cpu's are species only found in the rainbow kingdom who may have killed almost all the humans but as we know ( FOR NOW ) true zee and grizelda are the only humans, cats and dogs may not have been killed due to the fact they run the kitty thing but its all a theory, thanks for reading.
