Overdose on Regression

Far away in a secret forest lab
Turtwig: (Keroron Form) Eureka! I've finally perfected it. The ultimate in municipal instantaneous alterification!
Pikachu: The what?
Turtwig: Age Pills! If my hypothesis is correct, the consumption of these tablets will lead to the progression or regression of the ingester.
Pikachu: So if someone takes the pills they change ages.
Turtwig: In layman's terms, yes.
Pikachu: I wish you would have chosen a different form to explain this to me in because this form's too much of a poindexter.
Turtwig: (Changes to origin form) Says you. Now, we need to test them before we can allow them to be sold in stores everywhere.
Pikachu: We could advertise a drug testing in the news paper, and get volunteers to test it.
Turtwig: We can pay them very nicely too. We are former royalty after all.
Pikachu: Alright. I'll get a paper to run the article for us. (Heads off)
Turtwig: Oh the possibilities...

A few weeks later

It's another average, boring day, the kind where you want to stay at home and do nothing all day. Gill sits on his living room sofa, looking through his long list of endless bills.
Gill: Let's see...light bill, water bill, past due, jury duty, pay your fines, overdue, blagh blagh blagh. (Tosses them to the side) Where the world am I going to get the money to pay all these people? Pay them anything and they demand ten times as much the next time. (Grabs the paper) Maybe the want ads will hold something promising. (He begins to flip through)
Not surprising to him, the ads provide the same old jobs he'd seen day in and day out for the last few weeks. Nothing fun, and low paying. Everything looked boring, until he reached a brightly colored ad in the corner.
Ad: Want to make lots of money and help your fellow man at the same time? Join the Dark Republic today, and make yourself great.
Gill: Hmmm...that seems interesting.
Then he noticed the equally eye catching ad right next to it.
Ad: Want to make a bunch of money WITHOUT committing to something? Come down to Yoro's Pharmacy today to test out a new drug. Participants will be highly paid and only have to take pills with minimal side effects.
Gill: Now that's the kind of job I'd be interested in.  (Tosses the paper on the couch and gets up) Easy with lots of money. (Warps to town)

Meanwhile

Turtwig: How are we looking bro?
Pikachu: Not many people are in the pharmacy, and most of them look like they're just shopping.
Turtwig: Man. I thought people would spring at the opportunity to make lots of easy money.
Pikachu: I guess people are just paranoid of drugs or something.
Turtwig: Yeah maybe we should just- HOLY CRAP! (Freezes in his place)
Pikachu: What is it?
Turtwig: A really high spiritual energy just entered the area. I'd better hide mine. (Puts on a magical charm) Keep an eye out for anyone powerful looking.
Pikachu: Like that guy? (Points to a man in a black cloak)
Turtwig: YES! Duck! (They both duck behind the counter)
Gill: Well, this is the place. (Enters the Pharmacy) I wonder where the testing is taking place.
Pharmacist: Welcome. Can I help you?
Gill: Yes, I'm looking for where the drug testing is going to be conducted.
Pharmacist: Right over there. (Points to a table in the back of the store)
Gill: Thank you.
Gill strolls over to the table, but becomes confused when he notices that no one appears to be there.
Gill: Hello? I'm here for the drug testing.
Turtwig: (Hiding) (He's here for the pills?!)
A boy who looks around in his teens pops up from behind the table. His brown hair is ruffled around, as his light blue cloak slides to the side as he stands. Underneath is an all white outfit.
Turtwig: Hello. (Fixes his cloak) So you're here for the drug test?
Gill: Yeah, I need the money.
Turtwig: Who doesn't now a days. (Gets an all white bottle from under the table) Now, the instructions for taking them are easy. Take one and only ONE pill every six hours for one week, then return at the end of the week to show us if it worked or not.
Gill: O.K. So what do these pills do anyway?
Turtwig: Umm...there for...looking younger! That's it. Their age defying pills to help you look younger.
Gill: Oh. Seems odd you'd use them on someone like me, but o.k.
Turtwig: Thank you for helping us. We'll see you in a week.

Later

Back at his home, Gill is closely examining the bottle that he received.
Bottle: Age Pills. Look younger, feel younger.
Gill: Well, I guess it will be nice to look a little younger. Probably won't do much anyway. And it is for pay. (He opens the bottle to find it full of pink pills.) Might as well get started. (He removes one of the round pills from the jar, and pops it into his mouth)
The little pink pill is sweet to the taste. It's flavor like a delicious piece of candy.
Gill: Mmmm! Not half bad for a pill. (Takes out another one) I know he said only take ONE per six hours, but what harm will one more do. After all it's just an age defying pill. It's not like the types you can overdose easily on. (He takes another one) O.K. But that's it. Too many might have a bad effect on me. (Puts them up) I think I'll go play Xbox.

Later

Gill: (Tosses down the controller) I've beaten this like a thousand times. It's just not interesting anymore. I guess I'll just go make dinner.
He gets off his bed to go to the kitchen, but then notices that his pants are sagging down.
Gill: That's odd. These fit fine this morning. Perhaps gaming is actually helping me lose weight. XD (Heads into the kitchen) Now let's see...I've got some left over pizza from the other day still in the fridge. Guess I can just warm that up at eat it with a soda. (His sleeves slide over his wrists) Did I grab a big shirt this morning?
After having a few slices and a soda, Gill sits down to watch a little TV.
TV: Scientists believe that the universe was created by an event called the big bang, which occurred more than...
Gill: I swear my sleeves weren't this long this morning. Perhaps I stretched them out over the period of the day or something. *Yawn* Dang this program is so boring. Makes me wanna fall asleep.
TV: After this long period of no life, the first single cell organisms began...
Gill: *Yawn* Think I'll just...catch a few z's...til this program is over.

Turtwig: (Working on more regressive products)
Pikachu: Turtwig, we've got a problem.
Turtwig: What?
Pikachu: It's the Age Pills...

Before he knows it, Gill sleeps through the rest of the evening, and into the night. The sun begins to rise into the sky before he finally awakes from what he thought would be a quick nap.
Gill: (Eyes still closed) *Yawn* (Odd...I don't remember falling asleep with a blanket...I was just taking a quick nap) (Opens his eyes) Oh crap! I slept all night. Agh! What happened to my voice?!
Gill slowly looks at his hands, and then down at his now small body. He lies in his clothes like a child in their parent's clothes, bewildered.
Gill: How did this happen? I'm a little kid again. Wait...(His mind goes back to the pills) It must have been those pills I took.
He hops off the couch and runs back to the table with the jar of pills still on it, careful not slip on his shirt.
Gill: (Grabs the jar) Now let's see. Side effects include blurred vision and drowsiness. It says nothing about turning into a kid...It doesn't say if it's temporary or permanent either though.
GRRRRR
His stomach gives a loud growl.
Gill: Man, I'm getting hungry. (Looks at the pills in the jar) These tasted good when I ate them before. I bet they'll taste like candy again! (Begins to swallow several the pills) MMM! Their even better than I remember!
Gill continues swallowing the pills in the jar like candy until the entire jar lays empty on the table.
Gill: That was delicious.
GRRRRRR
Gill: But not that filling. I'll just go have some cereal and see if I can't fix this. (Goes into the kitchen)
Not to his surprise, his new found youth made him much too short to reach the top of the counter anymore, but luckily he had a stepstool.
Gill: Got it. Now for a bowl.
TV: (Begins to play his favorite daytime anime)
Gill: (Notices) Forget a bowl, I'll just eat it with my hands. (Quickly runs back and jumps in front of the TV with the box of cereal)

Later

An empty box of cereal sits beside of Gill, as his favorite anime comes to an end.
Gill: That was awesome! I wish another episode was coming on. (Remembers his predicament) Agh! I forgot I was supposed to be looking into this crazy regression. (Stands up)
His shirt now swallows up his small body, as the neck slides on his shoulders.
Gill: Am I even younger than before?! (Runs over to the bottle) Come on, tell me something.
He looks at the bottle, but all the words on it have becomes gibberish except for a few of the short words.
Gill: Why is this so hard to read now? (Begins to feel a rush of sugar fueled energy) Who cares what this says. I wanna play. (Throws it on the ground and runs off into his bedroom) Good thing I kept my old toys in here in case I ever needed to sell them for cash. (Opens up his closet to a large box of toys)
His box is full of the toys of his youth, mostly boyish things like toy guns and action figures, but it also had a few plushies too.
Gill: (Grabs two transformer toys, and runs back to the TV) (Talking for them)
Transformer 1: Raaa! I'm evil! I will destroy you and the planet.
Transformer 2: No, I will destroy you and protect the planted.
Gill: (Begins to make them fight) Boom! Crash! Schew schew schew! (Making fighting robot noises)
Another few minutes pass as Gills sits and plays with the toys, before they begin to bore him.
Gill: (Throws the toys down) I wondew what ewse I haf to pway wif. (Runs back to the box of toys and finds a plush tiger) Kitty! (Grabs it and runs back into the other room) Rawr! (Makes it pounce around)
*Knock Knock Knock*
???: (Outside) Oh I hope I'm not too late.
Gill: Who's dewe?
???: Thank goodness for skeleton keys. (The door opens)
Gill: Hey! Youw dat guy who gave me da piwws.
Turtwig: (Aww...he's so cute and small now!) Hey Gill...I came to get those pills. Turns out there not quite ready for testing yet. Appears I came a little late though. Sorry.
Gill: Why did da candy wegwess me?
Turtwig: Well it appears that if you take any more than one at a time, it regresses the body at a rate dependant on how many you took.
Gill: Huh?
Turtwig: (Picks him up) Never mind. I'll keep an eye on you until I can get a hold of someone who can care for you.
Gill: (Starts to fidgit a little)
Turtwig: (What's wrong?)
Gill: I hafta go potty. (Squirming)
Turtwig: Oh. 0.0 Hold on one second. (Digs into his bag and gets a diaper)
Gill: No! (Starts to squirm) I'm not weawing a diape!
Turtwig: But you need to, especially if you need to go to the bathroom. What if you have an accident?
Gill: NO! (Keeps squirming)
Turtwig: (Quickly holds him down and diapers him) There. And just for good measures...(Charms it) Now you can't remove it yourself.
Gill: (Angry)
Turtwig: Now if you have to go it's ok. I'll change you, and so will anyone else who cares for you.
Gill: I don wanna weaw diapews!
Turtwig: I'm sorry, but with you like this, it's for your own good. Othewise it would just cause problems.
Gill: Ugh...(Cringes)
Gills diaper begins to turn yellow, as a smell begins to enter the air.
Gill: (Tears up)
Turtwig: Oh no...
Gill: (Starts to cry) WAAAAAAAAAAAAAAAAA!
Turtwig: Awww...shhhhhhh...It's ok. (Hold him close and rocks him) I'll give you a change, and everything's going to be ok. (Sets him down on the floor and starts changing him)
Gill: WAAAAAAAAAAAAA!
Turtwig: (Gives him a pacifier, and finishes changing him) There now. All better.
Gill: *Sniff*
Turtwig: (Tickles his tummy)
Gill: (Starts to giggle) Heeheeheeheehee...
Turtwig: That's what I like to see. Smiling and happy.
Gill: (Cutely stairs up at him, and starts cooing)
Turtwig: Looks like your fully regressed now. (Gets a fold out play pin from his bag) I'll let you play while I look for a caretaker. (Sets it up around him) And let's not forget this! (Puts the tiger plush in the playpin) Have fun! (Heads off into the next room)
Gill: (Crawls over to the plush and gives it a hug) Ahh! (Well, I guess it's not so bad. There'll be cute baby sitters, no responsibility, and I'll get waited on hand and foot.)
He rolls over on his back playing with the plushie)
Gill: (I could get used to this)
