Long after mankind succeeded in committing mass suicide through the nuclear apocalypse, a peak achievement of the masculine ego of world leaders who like to fight the size of warheads, the earth left a quiet underground laboratory. There, a genius professor who was frustrated and bored to death created his last masterpiece before it became extinct, namely the Race of Mr. Plantae. They are not cacti, nor a miniature tree. Blue and Yellow are two cloned creatures that are purely extracted from selected herbal concentrate. A kind of herbal concoction that unfortunately is given life and artificial intelligence (whose memory capacity is deliberately set to be equivalent to the RAM of a tube computer). Physically, the two are identical: chewy, smelling of strong eucalyptus oil mixed with menthol, and have an expressionless face, similar to a Civil Servant who is serving in line for social assistance. The professor sat them down on an ordinary blue-yellow sofa. This sofa does not have an engine, exhaust, or artificial intelligence from Elon Musk. However, this sofa is the most advanced time-traveling machine and cosmic dimension ever. The mechanism was specially designed by the professor to spit out the history of human civilization. The sofa broke down completely before Blue and Yellow rolled the weed plants (wild weeds) like cigarettes, then sucked it deeply. The burning weed active substances in the body of their herbal extracts trigger a cosmic psychotropic reaction. The fly effect is what throws their consciousness, as well as the sofa they sit on, penetrating space and time. Humans used to be extinct because they slaughtered each other in order to compete for petroleum as transportation fuel. So, the professor made sure that his creation could jump the timeline of history only the "fly" capital using worthless weeds. A hard blow to the world oil industry.
