Humans are humans. There's not to much to say about them.
They were once the most dominant race/species, but after the North American Nuclear Incident dogs and cats began to develop and eventually take over as the dominant species.
Dogs and cats began to mutate after North American Nuclear Incident (which caused the creation of Good Boy Juice). They gained increased intelligence, lifespan, ect. They eventually outnumbered humans.
Lads are the nice, respectful creatures we all know and love. Carlos was the original, created by dough and secret sauce, but the rest were eventually created by him using the cat pencil.
Due to the fact that they can be created on the fly and are immortal (can't die of natural causes, but can from other causes) they swiftly took over the earth. (That makes it sound bad.... They just outnumbered the cats and dogs...)
They're basically lads, but radioactively mutated by an unknown force. They live around the ancient chasm, nucleotizing those who come close. They don't have feelings or a consciousness of their own. They attack without reason.
They're probably the biggest threats to the stability of society in Carlosland.
Very tiny boys that cannot be seen with the naked eye. These are basically prokaryotes in the lad world. Some are good, some are harmless, and some are dangerous.
They came long before the lads did. They mutated along side cats and dogs after the nuclear disaster.
Some say that Microbs were the ones to excrete the formula to the Council's Secret Sauce. But it's a secret, so you'll never know for sure.
