"You fucking ass, change me back!" Mark shouted. Then, he got an idea. Grinning, he flew up and grabbed hold of the amulet, quickly shouting "I wish Evan's body matched his jackass personality!"
Bill and Dan gasped while Evan scowled. "What the fuck, man?! Not cool! At least you can still talk in that form!" his hand cramped and he dropped the amulet onto the table, stretching his arms out in front of him. His middle fingers were thickening, growing longer as gray fur sprouted from the backs of his hands. He felt something squirming in the back of his pants and jumped up, awkwardly pushing his waistband down with his changing hands to reveal a gray-furred tail growing from the base of his spine. "I'm the one that found the necklace! I should get to decide what we do with it, not become a freaking ANIMAL before we even get started!" He suddenly jerked forward, his hips popping as his pelvis reshaped, and was just barely able to stick out his hands... no, hooves! in time to catch himself before he faceplanted on the basement floor.
Evan's shoes creaked and the laces burst as his feet morphed, heels lifting and stretching backward as his toes followed the same procedure his hands had moments before. Soon he was standing on four legs, back parallel to the ground and the remnants of his clothing in tatters on his expanded form. He stamped a hoof and flicked his tail, twisting his neck to try to get a look at his body. Something shifted and ground just above his shoulders and all of a sudden his neck felt much more flexible and... longer!
"Ohh shit... this is soo weeeiiird! You better change me baahhhhk!" Evan's face distorted, his nose broadening as his jaw pushed out, more gray fur beginning to cover his forehead and around his enlarging eyes. His short black hair suddenly stood up straight, disappearing from the sides of his head where the other boys could see that his ears had become pointed, flicking backwards and forwards as they grew larger and larger.
"Damn!" Bill laughed, nudging Dan. "It's like that scene in Pinocchio where all the kids turn into donkeys!"
Dan laughed along "Yeah, what was it called, that place where they went? 'Pleasure Island'? I don't think Evan's enjoying much pleasure right now, though!"
The boy-turned-jackass glared at his friends as they rolled around laughing, letting out an indignant snort before lowering his head to sniff at the carpet...
