The first thing Luke did with his new body was to work things out with his new heads--or brothers. Fortunately, all four body bros knew about what the magic clothes had done to the original--Luke--and decided to come up with names for each other. After some thinking, they discovered that they already had names--right-hand to left their names were Lewis, Logan, Leo, and Luke. While they all appreciated the names they had, none of them could shake how weird it was that they already had names--how was it possible?
All four body bros lost their trains of thought when they heard the front door open--Luke's parents and sister were home! They couldn't see Luke with a wider body and three extra heads! The body bros quietly snuck around to the wall--the one that nobody can see from the entryway. They were surprisingly coordinated with only two legs and two arms, considering that three of the bros did not exist until a few minutes ago. As they moved their body closer to the door, they made sure that only the rightmost head--Luke's--would be able to see while hiding the other three. Luke saw that his family had their backs to the living-room door, but that was not his main focus at the moment. He no longer had two parents and one sister: he was looking at four dads, four moms, and four sisters!
Apparently, Luke's new magic clothes did not just turn him into four conjoined siblings, but apparently his family as well! His fathers were Edward, Eli, Eric, and Ethan. His mothers were Abigail, Ashley, Alexa, and Alisa. His sisters were Sadie, Sarah, Samantha, and Suzie. Each group was conjoined with themselves: a wide body with two arms, two legs, and four heads each. They did not notice Luke, nor did his original family members seem freaked out by their new siblings. The dads and moms went into the kitchen, while the sisters went up the stairs, each group walking and acting as though they had been conjoined siblings their entire lives.
Luke and his body bros figured that was the case, until all four heads looked out the window. Out on the sidewalk were Luke's friends, twin brothers Mark and Max, but now conjoined--and with two more siblings! Apparently, the shirt that Luke made from the magic fabric had turned everyone in the world into one of a group of conjoined quadruplets, and nobody but Luke and his body bros knew!
Another question came to their heads: if the shirt turned the planet into a four-headed world, then what would happen if they took the shirt off...
