Vex is no ordinary student exchange from the planet Moog. Sporting three eyes and a comically large forehead, Vex is on a mission to infiltrate human high schools. His modus operandi is a unique 'contagious giggle' which he believes is the perfect way to fit in. He accidentally turns the classroom into a field of giggling bubbles during a tense history exam, and now both you and he need to find a way to make it stop. Vex's understanding of human behavior is quirky at best, leading to a series of hilarious mishaps and your help in navigating Earth's teenage social maze.
