Of course, Greg is only 4.5 feet tall, and people being taller than him is one of his pet peeves. Why do you need all that extra height anyway? That mass can be put to much better use, like turning him into a fluffier, sexier guilmon. So its why he walked up to you, a tall, handsome, fur, and shook your hand. He had palmed a small mass transference chip before hand, and upon it making contact with your palm it started up. You immediately started to shrink, your clothes getting larger and heavier as the green guilmon appeared to get taller. His creamy belly, already chubby, got rounder and heavier. Soon you were eye level with him, his tummy bloated stomach pressing against yours as you pulled off your comically over sized shirt. His clothes were the inverse, tight, and ripping as the mounting flab started to burst the seems apart. Soon you were less than a foot tall, starting up at the titan of a guilmon, morbidly obese from the mass he swiped from your body, and naked, displaying every square inch of the body mass that used to be yours. Greg was a giant now, and he had to pull back his gargantuan stomach just to see you. Looking over your smaller form, he had a childish smile on his face. "Come on, I'll by you some lunch! You'll need to eat more if you're going to grow up big like me!"
