The Supervillain Substitute

Fourth-grader Tyson and his classmates are pros at driving off substitute teachers. But their skills are no match for a guitar-wielding, ugly-sweater-rocking supervillain, who steps in as a sub for the week. He spins musical lessons and crazy experiments that have everyone in the class begging for more—everyone except Tyson.

He's got a mission impossible on his hands: rescue his class and, who knows, maybe even the planet, from the clutches of a mind-controlling sub. However, there's a little problem: Tyson's not exactly known for his honesty. So, when he tries to sound the alarm, everyone thinks it's another one of his tall tales. Just when he's thinking things can't get any worse, his sub starts dating his mom! Can he solve the mystery and save everyone?
