unfortunately, spin was something of an idiot! He didnt realize that he could just grow it using a super extensive blueprint feom the vast library of the cell structures of every living organism known to man that was stored in his personal laboratory on the 34th floor down in his estate.
of course he was too frightened to go into the outside world by HIMSELF so... he needed a partner, a nice partner, like a dog! a nice dog, a green spinach dog!!.... no that wouldn't work it would die the second it went outside. what with all the toxic gasses coming out of people's houses, there wasn't any real AIR outside. thats why most people just went out with a space suit or life pod or something similar so they wouldn't die as soon as they left and got hit by the strong solar winds. except for those guys who were too poor. they just used the extremely durable, extremely shiny platinum trash bags! pretty amazing right? shiny and everything. there were whole houses made of the stuff, sagging and blowing around barely tethered to the ground with tent poles and stakes...
but we're rambling again... oh yes! bioengineering! spin wanted to make a spinach puppy friend but he couldn't with no spinach plantations in sight! so he decided, "I'll go to a planet, where there's lots n lots of air, and water, and ground, that isn't covered in giant, metal, whatever those... robot... thingies are that look like giant spiders digging in the ground all the time yeah! I'll do that!!"
and so he decided to make a spaceship (in his family's giant hanger on the 3rd floor down of course) to take him all the way out into space to somewhere, who knows where, where there's actual ground to work with. not that he knew anything to do with actually growing real life plants... but, his perfect green planet waited, just a measly several billion dollars (and probably lightyears) away. "yes, a green place" he thought, "just like spinach!"
of course he didn't think about the fact that going hundreds of lightyears away to an alien planet might mean that there might not necessarily be a plant like the one we know of as spinach. but he's just a kid, he don't care, he wants spinach! he had nothing to lose! (yes, nothing to lose, except his family's giant estate.all his friends. all his family. all his money. and his thousands upon thousands of human and robot servants.)
so he went to the nearest rocket ship league to try to find an expedition that would bring him somewhere that was green. somewhere that was " spinach green".
