What's this button do?

"What's this button do then?" Amy said pressing down on what looked like an undo button.

"No don't!" Brendan protested to late as he braced himself for the same sparks that accompanied it last time. He closed his eyes and........

"Huh I guess it doesn't do anything. That's a bummer. I wanted to try out being super tall and buff." Amy said disappointedly

"Well thhhhhat's not the button I pressed the first time anyway but pleathhe can we not methh wiiiiiiiiAHHHHHHHH!!!!" Brendan screamed out as he felt a pain come across his whole body. Like a million needles stabbing into each and every part of his being but nothing he could do to make it stop.

"OMG Brendan I'm sorry!" Amy said crouching next to him and grabbing ahold of his hand. She watched as he squirmed in pain on the bed though she couldn't see anything wrong with him. He tossed and turned as one of his sets of bunny ears fell off..... wait. One of his sets? She reached out and grabbed the loose on and it just came away with her in her hand. She looked in her had as there was now and exact copy of the pair that set on Brendan's head. Next she saw that there was now significantly more hair than their had been a second ago surrounding him, and some seemed to be fake.

'The wig!' She thought. That would mean that... yes a second tail that was everything right?

"Chough! Chough! Akkkk! Ahhhh!! Thooo!" Brendan hacked as he spit out the fake teeth into his hands. "Wha.....What did you do?" Brendan questioned taking deep breaths as it seemed whatever had happened passed.

"I... I don't know. I'm so sorry I... I just pressed this button." She said as she showed him the gun. But she couldn't help but notice that in his mouth still sat a set of large buck teeth.
