Educate me please. 
[/quote]

It's best explained by a song I've heard.

Octopi have started using ocean trash as tools
They're grabbing cans and bottles to make stuff that's pretty cool
They're smart enough to build houses and camo with your garbage 
So don't forget this warning as your refuse is discarded

Please stop littering
Before the octopi start building elaborate mech suits
And launching full-scale land assaults on our coastal cities
For heaven's sake don't drop gun
Or society will soon be overrun

(Don't know who originally made this, but I heard it from some guy called Jordan Keyes on YouTube)
