You struggle with the door again, but it won't budge. You're trapped in this new world until you can find another way back home. Frustrated, you cast about, hoping to find the entrance to this world's version of the fun house. Things seem basically identical, but you can't find you're bearings, since you came out at a completely spot than you went in. To your surprise, you can't actually read any of the signs. It looks like English, but it's all nonsense. Even the letters are oddly unrecognizable, though you can't put your finger on just how. They SEEM like the same letters, yet you can't even guess at their meaning.
You realize people are watching you as you try to make sense of it, though the interest is mild. You haven't seen any yet, but there must be other humans around, or else they'd be freaking out. You decide to duck down an alley between two carnival buildings, to think things over out of view. Once you've gotten out of sight, you decide to pull out your phone and see if you can figure anything out about this new world via the Internet. It's a long shot to think your phone would even work here, but it's a start. Unfortunately, it seems to be missing from your pocket! In fact, so are your wallet and keys. Somehow you must have lost them in the maze!
Your concern is short lived, because a sudden cramp distracts you, seizing up your whole body. You contort and twist, falling to your knees, your muscles spasming, your bones aching. You watch in shock and surprise as your body begins to change. The first, most obvious signs are your hands. Your fingers shorten, your thumbs migrating back toward your wrist, rapidly making it physically impossible for you to functionally grip much of anything. Your nails grow thick and longer, like blunt claws. And as your clothes begin to hang on your body, you realize you're growing smaller as well.
As your body shrinks, you tumble out of your suddenly loose pants, losing them along with your shoes and socks. Your feet have also changed, but if anything they've grown longer, while your legs are rapidly growing shorter. Tangled in your shirt now, you tear it off in frustration, leaving you completely naked. You attempt to stand, but find it difficult, ultimately resting in a squat on your long, thickened toes. From your new posture, you realize that your arms have grown longer, or seem to have. It's now easy, even natural, to rest your altered hands on the ground for support as you sit.
Once the cramping has subsided, you take stock. It's hard to tell just how small you've gotten, but at a guess you suppose you're the size of an 8 or 9 year old child, though you seem to be fully mature, despite your alterations. Your sexual development is not in any question whatsoever, considering your equipment is hanging out for all to see, and are some of the only parts of you NOT to get noticeably smaller. Morbidly curious, you approach a puddle from a spilled drink, fallen from a dumpster, your movements seeming like an odd cross between a quadrapedal crawl and a chimp's knuckle-dragging gait. In the dim reflection, you can see your face well enough to recognize it's almost just as you remember it. Your eyes seem bigger, and have taken on a dull sheen, and there's something odd about your jaw... bigger teeth maybe? You touch your face with your altered, paw-like hand. You still seem human, of a sort.
Before you can make sense of what's happened, a small group of dog people come around the corner. One of them, clearly a patron of the carnival, resembling a two-legged shih-tzu, points down the alley toward you, saying something incomprehensible to the other two. An anthropomorphic terrier, apparently a manager of some sort, directs the uniformed golden retriever man in your direction. He nods and comes at you, making friendly, reassuring noises, with what you'd swear was a collar and lead in his hands. You only have a moment to decide what to do.
