What about the next set of combo squashers?
Matt: 15 years old, 7'9, 2,000lbs, brown hair, hazel eyes
Calvin: 15 years old, 8'0, 2,000lbs, dirty blonde hair, blue eyes
These two are best friends since kindergarten, and they've just gotten bigger and fatter, after they tried out the bottle of potion Calvin's Dad had made, which worked surprisingly well. So much of the surprise both had, it was only a matter of time before they would use their massive girths to squish anyone as they well please, starting with Matt's 9 year old brother, who had been a pest all this time.
Lucas: 11 years old, 7'5, 1500lbs, dirty blonde hair, brown eyes
Drew: 8 years old, 7'0, 1,000lbs, dirty blonde hair, brown eyes
The two brothers were at school where they would volunteer to take part of the science experiment from a scientist. That experiment worked wonders, and it caused both of to grow a lot fatter, much to the surprise to both the students and teachers alike. But now that they're so huge, both had that same idea and could their advantage to push, bump, and squash anybody in its sights, and they liked being so big too well.
