Have you ever had a terrible teacher? Ever had a terrible teacher?
Imagine working in silence, cancelled playtimes and a temper that can bring you to tears. Sound familiar? Well now imagine dart pens, sonic whistles, desks with secret compartments, a stapler for injecting sleeping potions and rocket-powered chairs. Not only is this teacher terrible, but there's also an evil plan afoot and perhaps the children in his class are the only ones who can help.
