Abuse of power

Koln noticed the person from earlier with the drink, but wasn't overly bothered about it. However, what did surprise him was seeing another person come out with the same drink, also taking a sip immediately.
"BLEGH. Apple..." George immediately put the drink in the bin. He hated apple.
"..." Koln shrugged, yawning and thinking of what to do.

Cyan started to drink, it tasted amazing! he kept going until quickly it was all gone.

"You must really like apple..." George said to Cyan, but a little sick to say it because, obviously, he hated apple.

Cyan looked up, a bit startled
"Yeah..." he said, not noticing a small patch of green appearing on his hand.

"..." George's eyes all of the sudden went straight to his hand. It stuck out pretty clearly for him, almost unmissable.

"What is it...?" Cyan asked, as it started to spread.

"Uh..." George was in too much shock to say anything. All he could do was point.

Cyan looked at his arm, and gasped
"W-what the hell?" He said, as he felt a sharp pain near the end of his spine.

Koln slowly turned his head to Cyan, watching as he began to change. George thought that the drink was making him hallucinate, but Koln simply thought he was still dreaming.

Cyan gasped in pain as a large yoshi tail grew, his skin was getting more like orca skin than scaily, but this was due to the way yoshi's skin looks, the skin continued to change colour too.

Koln and George couldn't believe their eyes. Koln thought 'maybe it was the drink?'. He didn't hesitate to throw the other can in the bin next to him, but neither of them could take their eyes off of Cyan.

Cyan had tears of pain in his eyes as his nose started to "inflate" his belly also got fatter as if he had eaten a load of food.

"What da hell is going on?!" Koln asked, highly shocked about the current event. George was too surprised to even think about what to do.

Cyan's clothes ripped due to his size, his face looked distorted as his features were starting to re-arange for his new body, all of his hair fell out.

George started to feel a guilty laugh coming... he just couldn't take how silly Cyan was starting to look. Koln quickly went to go call for a doctor.

Cyan's head was now fully changed, including his tongue, his changes stop and he is left as a fat, humanoid yoshi, all he can do is stare at his new hands in shock.

"..." George fell back, crying and laughing and on the brink of pissing himself. He could not believe what he had just seen, but the final result was completely the opposite of what he was expecting.

Cyan glared at him
"A-aren't you gonna help me?!"

George looked at him, sitting upright.
"It's not like I know what the hell to do!" He said, trying to hold in his laughter.

Cyan poked out his new long tongue, as horrific as this was, he did find that being a Yoshi was kinda cool.

George was shocked by the new tongue.
"Jesus, you're like... Yoshi!" He remarked, immediately bolting up on the spot.
"Oh, COOL. How did you do that?" He asked, eager to find out.

Cyan stuck it back in
"I think it's because I am a yoshi...?" Cyan replied, still confused.

George walked over to him, taking a closer look. He poked him on the nose, just to make sure he wasn't imagining this. So far so good.
"Wow... that's awesome!"

(XD would help if there was someone who made their character be one of the people who capture the transformed people, ah well, I might do it...)
Cyan smiled
"Thanks!"

(I was just gonna do that.)

A bear came walking round slowly, a bothered look on it's face as it looked at the yoshi.
"... I see we are on da same picture." Koln's voice sounded from it. George looked round to it, then continued to laugh even harder.
