One day on a exhibition with my school me and a friend decided to depart form the group and go in the woods, planning to later on come back and scare upon them. We also got some ghost masks just so they stuff their pants. We were going to go at cabins, and we were basically just taking a alternative route, the theory was that while they would be going towards the cabin we would be gone missing, and then when they reach it we would suddenly pop out with our ghost masks.
Unfortunately, my friend hit his leg really bad and looking back to our path, well, we didn't particularly make a path so we had no idea where we came from... I had to go forward to the cabin and call people back for my friend, but I couldn't just leave my friend here, and I am not that strong to pick him up either for all the path we had to take. I didn't hear anyone scream for us or anything, just the little buggers in the bushes and stuff. Me and my friend concluded that he stepped wrongly and thus he can't walk on one leg. This wouldn't be a problem on a straight road but we were in the woods with rocks and grass and bushes and stuff like that. We still tried, sort of, leaving the masks back because that's all we had with us and I had nowhere to hold them (unless on our faces but we didn't think about that back then, it was really a urgent situation and we considered to get them back later, seeing now we ripped parts of bushes etc. and it did look like a path, that someone walked on) anyway, we somehow actually managed to get to the cabin, except that no one was there. We assumed that they were looking for us so we just settled in the cabin, except no one was in there either (like, the guy who's supposed to look over us or anything). I went back in the woods to grab our masks, managed to find the path, and, unfortunately, the masks aren't there. Hearing something in the bushes I have had quickly ran back to the cabin, still no sign of life, looking back in the cabin my friend wasn't there either. In the attempt to not lose my stuff I had to conclude the group came to the cabin and then took him away to a hospital or something, but there still wasn't absolutely no one in here. I quickly ran out to the main road, hoping to get back with the group. I reached our bus, and I haven't met anyone from the group on the way back (the bus wasn't able to drive straight or next to the cabin, so it was left near the bus). It was about 8PM and the sun was setting, I quickly looked over at the bus, next to it, etc. Other cars were circulating but there was nothing else to it, the group was literally gone missing from my path. Remembering where I initially started this "plan", I decided to take the same road I took at the start. Eventually I found the ghosts masks hanged on a tree. I have not left them on a tree but on the ground, after which I marked the path with the bush rip and stuff. They are in the exactly same spot as I initially left with my friend, and when I checked previously on the path I took back. I slowly grabbed them, the both masks had some reptiles under them which I scared my stuff upon. I assumed someone did a counter-prank or that my friend's leg wasn't even broken to begin with. I literally ran my stuff back to the cabin as I head some violent bush rustlings, I didn't want to look like a fool from the prank but nor did I want to /lose/ it. Coming back to the cabin, I seen lights inside. I ram down the door. Get on the floor. Everybody walk the dinosaur.
