The kids in 5C will never be the same....
What happens when your teacher doesn't show up for class? You get a substitute, right? And that usually means a couple of days of smooth sailing: no home- work, no tests, no problem. At least that's what Allan and his friends thought before "Mr. Monster-Sub" walked-or crashed-through the classroom door.
Mr. Monster-Sub is the meanest teacher on the planet-and that's on a good day. In his class there's no recess, no talking, no nothing. And there's a chance the fifth grade's real teacher will be gone for a week! Now what? Well, Allan and his friends have to come up with a plan-and fast-or they may not make it out of the fifth grade... alive!
