Boomer and Brady are flattered when a pair of cute Queens from the neighboring island of Sununu compliment their latest ridiculous invention and ask them to be the Kings of Sununu. However, the Kings soon realize that the Queens and their kingdom are victims of a dumb-curse. In order to help cure the entire island of stupidity, Boomer and Brady must solve the Statue's riddle. When Brady gets the riddle wrong so the girls could still admire him and Boomer, the Statue puts the dumb-curse on King Brady, forcing Boomer to get help from Mason, Mikayla, and Lanny to solve the riddle by sunset or else they will be dumb-cursed.
