Abuse of power

(Oh, sure, go ahead :D)

Cyan smiled and looked at George
"Hey, didn't you have some too?"

(You sure you don't want to do it yourself? You know, if you don't want to then I'll be fine with doing it.)

"... Only a small sip." George replied, but he wasn't feeling much different at all.

(Yeah, it's fine don't worry :P)
Cyan shrugged
"I guess it only affects people who drank all of it..."

"..." George, strangely, felt as if his surroundings were getting larger. "Well, now that you mention it." He could feel his mouth starting to protrude out and harden, along with the hairs on his skin turning into feathers. The mouth part was the most painful.
"Well, dere goes his transformation." Koln said.

Cyan watched.
"Not so funny now is it?"

After his arms thinned out as rows of large wings grew on his arms, his hands disappeared. The legs started to turn yellow as the skin hardened, his toes spreading out and his heel going back until he was finally morphed into a chicken.
"... This is awkward..." George mumbled to himself.

Cyan fell on his back laughing
"hehehe! you look rediculous!"

"Alright, alright, I'm sorry..." George almost clucked, his head acting more twitchy than usual. Koln looked around, realising everyone had already ran off because of the mutations.
"Free food!" Koln ran on all fours into the store, taking a look around to see what he could eat.

"Good idea!" Cyan said, running after him, aparently yoshi instincts were included,

"Ugh..." George awkwardly walked into the store, his head staying in one place as he walked forward.
"Come on head, move it." He bobbed his head forward, also wondering how chickens are able to walk like this.

Cyan was already grabbing fruits with his tongue and stuffing his face with them, this body had it's upsides.

Koln was busy in the in the ice cream section, as was George in the fish section.

Cyan burped loudly.
"This isn't so bad!"

"Maybe not for you!" George called out, ultimately having trouble trying to carry a simple bag of Haribo.

"Think of it as Karma!" Cyan said.

"... I hate Karma." George mumbled to himself. At that time, he could hear the shop doors open and close. It confused him.

Cyan was too busy eating to notice, he felt like he could eat forever.

George could hear footsteps... slow and rather eerie footsteps.
"Uh... guys?"

Cyan still ignored him, finishing off the fruits.

George walked down to the end of the isle to see who had walked in. To his shock, there was (Hold on a minute... I'm not sure whether to go with a kind of catcher of your idea, or to make my own up...)

(Up to you, don't mind :D)
Cyan burped loudly as he finished.

(Okey dokey lokey)

To his shock, there was a person in a dark green leather gas suit, with a black gas mask, black wellies and black gloves. The thing that worried George the most was the net - there appeared to be an electric rod extending out from one end of the net.
"THERE'S A FREAKING CREEPY GUY HERE!" George yelled, turning around and running as fast as he could. The man ran after him, his breathing sounding very heavy.

Cyan looked at them
"holy crap! run!"

Koln was far off in the store, sniffing up the fish and eating the raw salmon.
"WHATDOWEDOWHATDOWEDOWHATDOWEDO?!" George yelled as he ran, their assailant getting nearer.

Cyan yelled again
"Just run dang it!" he then stuck his tongue out and poked Koln to grab his attention.
