Derrick stared at the wall of the "shower". This HAD to be a dream, a crazy dream. He must've fallen asleep on the way to the resort. But it felt too real. This COULDN'T be real, though. Could it? Derrick cleared his throat a bit. As the computer's voice got to the end of the list, and began to repeat them, Derrick piped up.
"Uh, the first one," Derrick stated. "Merman with, uh, dolphin tail." As soon as the words left his mouth, multicolored bubbles began to rise from the drain at the bottom of the chamber.
"Choice confirmed. Proceeding with transformation," the computerized voice responded. Derrick looked around in a panic as the bubbles, which only previously trickled up, began to foam up and mix with the water.
The chamber began to spin, first slowly, then quicker, which began to churn the bubbles into the water. The strangest feeling came over Derrick, his head becoming light and his breathing ragged. He was burning up! His eyesight began to get hazy, filling with color and light. There must've been some sort of drug in this water, he must be going crazy!
His legs felt limp, he could no longer move them. Then, he looked down and, eyes wide, he noticed his skin below his waist turning grey and gaining a shiny, almost rubbery texture to it. His upper body seemed to be changing too, becoming stronger-looking and more muscular. His ears and back of his neck began to tickle at hair that seemed to be growing and elongating, touching his ears and neck where they once did not. His legs now fused together, and his feet flattened and spread out, turning into the flukes of a powerful-looking tail. A strange sort of pleasure erupted from the entire experience. Through this whole experience his heartbeat and breath raced, and finally, in a sudden burst of color, light, and pleasure, he let out a moan...
...and now he didn't seem to be in the chamber anymore. He was now in what looked like a deep ocean, which didn't resemble any ocean he was familiar with. His took deep breaths, swimming in place, and he looked down at himself once more. Sure enough, he was now a dolphin merman, but more had changed than simply growing a tail. As the computer told him, it would be an hour until he turned back. Then no more transformations for him, he could get back to his normal vacation.
