As you search the suit for anything that looks like something you enter through, you notice a crease above the suit's tail. You ask the clerk, a very attractive young woman, if she could get you a stepladder.
"Of course, and do be careful getting in!" she said with a slight smirk, before going into a supply closet to retrieve the ladder you asked for.
"Thanks, Miss..." you ask flirtatiously.
"I'm Rose, nice to meet you" she replies before wandering back to the register.
You decide that you should put on the suit, so you strip down and leave your clothes on the floor in a pile. You begin to ease your body into the crevice in the suit, and soon your legs are all the way into position. It feels a bit tight, but not constricting at all. Then you pull yourself into the chest cavity, and insert your arms into their correct positions. The same sensation as before occurs, except that you feel a weird pulse in your arms, and lose all feeling in your pinky and ring fingers. Not really caring, you finally insert your head into its corresponding hole. Finally you can see again, but something feels odd. Your feet feel cold, your vision is much sharper, and there's something hitting you , which shouldn't happen through the padding. You turn and look in the mirror and then it sinks in...
You really are a T.Rex now!!!!!!!
Your mouth is wide open with shock (and drooling as well) as you see your new face. And than you see your tail. Then you get hit in the face by your tail. And then all of this really sinks in.
You don't feel the foam like you did before. "It must be some sort of bio-adaptive compound" you think.
Rose walks back in out of nowhere and says, "How do you feel, Big Guy?"
Worried you may no longer be able to speak, you manage to mumble "okay", but much deeper than you could before.
Suddenly realizing the significance of that one simple word, you are elated! They won't stick an intelligent being in a cage!
"Rose, would you mind accompannying me to lunch at the cafe?" you say confidently in your new, massive, scaly body.
"Sure, but I never caught your name!" she replies.
"My name's Roy, but please, call me Scaly"
