It was a dull day in Domino as Mokuba wondered around the Kaiba mansion. He was bored out of his mind!
"Maybe Seto's doing something interesting." Mokuba said walking towards Seto's laboratory. He cautiously opened the door just in case Seto didn't want to be bothered. But no one was there.
"Strange...I thought for sure Seto was here. Well, as long as I'm here, I might as well look around and see what he was working on."
He searched throughout the place, but didn't see anything new. He was about to leave, when something under a sheet on a table caught his eye. He pulled it off and found some kind of ray gun. He picked it up examining the details and found it was a very simple device. It had two letters on the side and a dial pointing in between the letters. He fiddled with it and pointed the pointer to G. He fired the ray and it hit a mirror and blasted back at him engulfing him in green energy. He quickly let go of the trigger and set the gun down. He was feeling a litle dizzy. But soon he was fine. He stood up and something seemed ...wrong. Everything was a lot smaller! The table the gun was on had been at his chest, it was a big table, and now it was around his knees! He grabbed the gun and left the room crawling out through the door looking for a new target. Who to grow or shrink?
