Here's the nutshell of the backstory of this story, it's the storytelling of his p.o.v.
Helped written by my sister.

"Hey, I'm Jacob, Jacob hills. I went from skateboarding in the woods, to be in a world full of colorful people as a cat.Let me give you some background. My friends and I were at a skate park, and having me, the coolest of the bunch, practicing my sick kickflips. The next thing I know after misstepping on my board, it rolls into the street and then burst into splinters under a car's wheel.After mourning over at my now deceased board while my friends laugh at my crushed spirit, we head to the local gas station. I purchase us some chips, drinks and a packet of beef jerky, if someone doesn't like what I grabbed.

I head out and noticed a skateboard just left there, abandoned. And this isn't some old board, its like brand new, as if it was just made.It had a camouflage design with a cat head that had 2 machine guns under it, like skull and crossbones. I questioned the clerk about the board out there, he said he'd never seen it there and no one out there the last time he looked. I got close and I had a feeling that this board was mine as if it was calling me.I told the guys, they thought it was a lucky find, I tested it and it was awesome! It had some wording on it that said,

BORN 2 LOSE

COUNTRY TRASH PROUD

DRUMMER

SK8 AND DESTROY

SK8 2 CR8

BOUND FOR GLORY

Something happened in between to where we went to the woods, got drunk from a six pack that one of them had, fucked around and one of them grabbed my bag, and started running.While I was trying to get my bag back, it reminded me of some ninja game where at one point you're running through the woods. I don't remember what it was called but it was pretty cool. The dude stops, lifts my bag high and ways it a bit, then fucking tosses it onto a high branch that looms over the old mine hole from the 1700's.I don't if it was the beer or the dude was just a pure asshole, but he thought it was the greatest thing to do.

I went after that bag, it had the skateboard and my phone in it, plus some good snacks and my weeks paycheck.It was pretty high but not to difficult, so I started climbing towards it, even though it was becoming more thinner and dangerous. I'm over the hole by now and it's just about to slip in, but I got it in the nick of it! I was so proud of myself.

Then I heard crackling behind me.

The branch was snapping! I started back peddling fast as I could, but I wasn't fast enough.Falling into the 'mine shaft' was like tripping on acid while going through a vortex at hyperspeed.Then the next thing I know, I'm in the grass, with fury arms and legs."
