With the School Invention Fair coming up, Sam is determined to invent the best invention. First, he builds a robot that’ll clean the toilet (but it refuses). He tries a fart fan (but that just creates a mess at lunch). Will Sam come to the fair empty-handed, or will he create something great and win a prize? Sam is determined to come up with the best invention for his school's invention fair, but he cannot figure out how to make any of his ideas--including a robot that can clean toilets and a toilet seat for his cat--work.
