You decide to follow your instinct, and by instinct you mean marking each corner with an arrow pointing the way you went to stop you from going in circles. You have to say, your surprised your sharp nails have proven to be useful in this regard. Well, that and for itching your ears that kept tingling as if they were stretching out. Left, left, right, straight, right, right, another left...this went on for what felt like hours, and yet you hadn't seen a single marking indicating you'd ended up circling round, nor had you seen anyone else or any sign of the exit. Trip. You fall over, landing face first on the floor. Sitting up, you rub your nose as you feel it swell up, extruding ever so slightly further outwards, yet not enough for you to notice it as anything more than swelling from the fall. You look back to see what tripped you, and find nothing. Odd. Standing upright once more, you continue onward, yet it's only a matter of time before you trip again, smashing in to the ground as you feel your front two incisors dig in to your bottom lip as you tumble. Rubbing your mouth, you find that your incisors were jutting out quite a bit, to the point where you couldn't get them to stay in your mouth. "Great, now I get to add damaged teeth to the list of bad things that have happened in here," your inner monologue muses. You start to regret sneaking in a little. After all, this would never have happened had you just stayed out altogether. Still, you right yourself, and proceed.
It's not even five minutes later and you find yourself tripping again, and this time you figure the cause.
"I can't believe all this time I've been tripping over my blasted T-shirt!" You yell as you start ripping it off in a hurry. It takes little effort, and almost slides off completely without even trying. You sit up, but encounter a jolt of pain that you can't quite place, so you just lay on your side. "Weird," you mutter, "I could have sworn that it felt like I was sitting on myself just then..." unbeknownst to you, by now your tail had lengthened fully, and you had just managed to sit on it whilst somehow remaining blissfully unaware to the fact you even had it. With your T-shirt off, you're now stark naked,and though you feel as though you should be embarassed, you can't help but feel it's better this way...more natural...and at least you don't keep tripping up over that T-shirt! You try to stand, your T-shirt now out of your way, but you just feel a sharp pain in your back and have to get back down. You wait a few seconds and try again, just to be met by that pain again. "Great, JUST great!" you think, "and now I've injured my back and can't even walk upright. Guess I'm going to have to literally crawl out of here!"
You move much more slowly on your hands and knees at first, but eventually begin to get the hang of moving without standing upright. Somewhere along the lines, you found it much easier if you just stood on the balls of your feet rather than your knees, and after that you were moving around at speed in no time at all. Still, eager for an exit, you continued with no hindrances (with the exception of scratching yourself every now and again when you start feeling an itch and a bit of extra warmth.) You start to think you'll be finding the exit in no time when you round a corner and find yourself face to face with a large piece of fabric. More specifically, your T-shirt. You squeak in defeat, slumping your head down as you realise you've at some point gone in a circle. You have no clue how long you've been in here, how close you are to the exit or whether you'll ever get out. Your lowered head is looking straight at the T-shirt, and if you didn't know better, you'd have sworn it was larger than you were!
Just as you give up hope, you smell something. A small, distant smell, but a smell nonetheless. With nothing else to lose, you attempt to follow the scent, reasoning it's just as good a chance as any at this point. As you near the smell, you begin to recognise it more and more; food! And since you're in a funhouse, food is most likely going to be outside, which means you'll find it at the exit! You begin to move faster, the motivation of food driving you onwards, giving you a last bastion of hope. Finally, after what felt like days, you find yourself in front of a small pedestal with cheese on top, a sign overhead reading "Finish," and with a squeak of delight you begin eating the cheese.
After only managing to eat a small fragment though, you feel a rough hand grab your back and lift you up.
