"What should we do now?" Jake asked.
"Well, I kinda liked it when we were conjoined, bro," Dan replied.
"Hey, I wanna be conjoined with someone!" Marcus added.
"We could do it, bro," Jason told his brother.
"What about me?" Kate asked. She was the only girl.
"Maybe we could give you a sister?" Dan wondered.
After fiddling with the Chronivac, the changes began. Each pair of brothers moved side by side, and morphed into two wide bodies, each with two heads on their broad shoulders. As for Kate, her body widened, and a new head appeared next to her own.
To recap, Dan and Jake were now sharing a body, Marcus and Jason were sharing one, and Kate was sharing one with her new sister.
