Sebastian J. Mouse was tired of being stuck in a lab. He wanted what every mouse wants: Freedom. Night after night he plotted, day after day he planned, but no matter what he tried, he could never find a way out. Either the lab workers would catch him, or the lab's pet cat would chase him back to his cage. But then, one fateful morning, a new mouse joined the party...except this wasn't a mouse, it was a guinea pig named Ralph. Bigger, stronger, faster than all the other mice in the lab, Sebastian looked at Ralph and knew he'd found his ticket out. There was only one problem...Ralph liked his new home and didn't want to leave all his newfound friends. Convincing Ralph to help him leave will be Sebastian's toughest challenge yet!
