Apocalyptic Octopus

We are clicking on this Octopus game, and I didn't think about its meaning initially.  Someone told me the street is blue because it is water and that's how we get octopuses.  Then I had a deeper thought, did it mean the whole world is under water, and the octopuses are playing with human sports, human cars, human games.  And in time, they even develop nationality... 

In this case, the most unrealistic bit of this game is that, electric cars are famously hydrophobic!
