George activated his monster transformation first.
His head expanded at the top and grew onto a stalk, taking his eyes with it, which merged into a big eyeball which opened up on the head.
His ears grew big and round, almost monkey-like.
Then, to David's surprise, George's hoodie, trousers, and shoes, all disappeared! Even the clothes that were under them, a tan shirt, white heart-patterned boxers, and dark green socks, disappeared too.
David's eyes nearly fell out of his head. "What's happened to his clothes?" he asked his twin brother.
"Cartoonish MonsterMen don't wear clothes, so, US Monster men often strip off our clothes, or they disappear, or destroy themselves as we tf." Dennis said.
"But do not worry." he added, "the clothes magically return to their owner's homes, as if they were never destroyed to begin with."
David and Dennis both watched in awe as George's feet grew to double their size, gained dirty jagged green nails on the toes, gained spikes on the heels, and the saw George's thin lanky naked body get thinner and taller. David saw George's penis slurp right into his body, and his scrotum shrivelled up. On his hands, His fingers grew longer, and his arms became thinner and longer, as did his legs, and 2 more pairs of long thin arms, with hands with long fingers on them, grew from his body.
and finally, huge bright pink spots appeared on George's body. His skin still remained the same colour, though.
David had witnessed a monster transformation up close. He had to believe this was a bizarre dream.
"Tada." George said, raising his 6 arms, triumphantly. "I have become a monster.
David had to pinch himself to see of he was dreaming.
