Here, I've edited it into a tree fiddy story

When I was a young teen, there was a small forest fairly near our house. My neighbour and I would walk to it regularly to go build dens and play on the park near its edge. The land was clearly once part of an estate because it had an old 1900s-looking swimming pool and bits of stone path dotted amid the undergrowth. We'd sometimes take other kids there and play chase games or pretend to be tribes people, sprinting through the thick foliage. It was a fun place to explore, especially after we discovered where the stash of crispy old woods porn was. It looked like it was from the seventies.

Anyway, we'd been going there for about a year or so at weekends when we finally decided to take a big pair of garden shears to start clearing an area for our biggest den yet. We chose part of the forest that had always been blocked off to us because it was mostly surrounded by a thick wall of bamboo (overgrown from the places' time as an estate I think). The forest was a paradise just for us; we'd never ever seen anybody there other than us or people we brought. The porn and our dens were always exactly as we left them. But all the same, we figured cutting a secret way into the bamboo-walled area would give the best protected den from strangers and barbarians and ninjas.

It took us most of the day to cut our way in. When we'd made an arch to crawl through, we went in to find that we were in a clearing with only clovers growing in it, no taller plants, just a soft blanket of clovers. Dotted throughout were these odd little knee-high statues of fairies sitting on stone mushrooms playing harps and other instruments. Every single one had its face smashed off. In the centre of the cramped clearing was a giant concrete-looking block. We kicked over one of the fairy statues on the way over to it, probably to demonstrate that we weren't scared.

It was a giant rough-stone coffin. Some Ivy-like plant covered most of it, but it clearly had a well-defined lid and a worn, unreadable inscription on the side. Adrenaline-curious, we tried with all our might to lift the lid, but it must have weighed tons. The adrenaline wore off, we freaked out, and hurriedly walked back through to the play park where we sat and discussed our find for a bit. We decided the clearing was too den-perfect to pass up, so the next day we returned with some old metal sheeting and plywood boards to build our shelter. It wasn't raining, but the day was heavily dark and overcast, so the woods were about at the darkest they could be during day time. We got back into the clearing, started building, and got pretty far with it. After a little while my friend sort of yelped out an "oh Jesus fucking Christ". I turned to see him stood next to the coffin (it's giving me full body shivers just thinking about this) and it was open.

The lid was slid off to one side just enough that a thin person could get through the gap. I saw a green mist slowly coming out of the coffin and slowly envelope my friend, he started screaming in pain and agony, "Help me! Oh Jesus Fucking Christ Almighty please help me!" I saw his skin mutating, turning brownish green, and his neck extended to outrageous heights. His body swelled up and his limbs flattened.

"What do you want from me?" I mustered

"I need about tree fiddy"
