"Let's go deeper into the woods", Lindsay says immediately. You almost warned her that it could be dangerous, but forget it. You both expected dangers when you came here. So you stepped off the beaten path, brushed a blue-and-white fern out of the way and crawled through the underbrush. It didn't bother Lindsay in her tomboyish jean shorts and shoes. You had a skirt, which kept catching on branches and ripping, and your flip-flops were long gone in less than a minute. Lindsay was smirking and it seems she was amused by your ragged appearance.
Although you were able to see a wide variety of alien beasts, one managed to stay just out of sight, watching you from afar. A humanoid alien who was extra buff and hairy, sported a tail like a chimp, and was nude except for a tool belt and a wrist band on his right arm. The wrist band read "Park Staff", only in his native language. He watched you and Lindsey as carefully as a hawk. But you never knew his presence until it was too late to do anything about it.
Back inside the jungle, the underbrush was still a hassle and even Lindsay was tired of drudging through it. She was unusually quiet, since there was nothing to say that wasn't already obvious. Luckily, the sound of running water was heard and in no time, you were both free of the brush and standing at the edge of a fresh water stream with some truly strange aquatic beings living in it. Lindsay had all her excitement back, admiring the... fish? and chatting at a rapid pace. "Ooh, what's that one? Never seen anything that glows purple. Wonder what they eat?" Suddenly, she became silent. There was a wicked-looking dart in her back!
"Lindsay! Are you alive, speak to me!" You cry out, desperate for a positive answer. With a weak voice, she replies "Don't worry, just... sleepy..." and promptly drops to the ground for a nap. And you don't get a chance to react, as you feel a sharp pinch in your own back, followed by intense dizziness. Before you sleep, you notice a caveman or ape jump down from the trees and approach you with a device. Cut to black.
Thankfully, you are able to wake up. It takes a second to shake off your light-headedness, but it goes away on its own. Then a startling shock: you've been stripped utterly naked and left in the dirt! And Lindsay too! In a panic, you rush to wake her up with a hard shake. She blinks her eyes twice and yelps at your nakedness, and just about falls over backwards. You both talk over each other in total confusion, but get no answers. "Why?!" "Have we been molested?" "I dunno!" "How do we get home?" There's only one clue to your fate, a barcode and alien writing tattooed on both your wrists.
