Three Crowns and the Dream Sofa

Despite Earls plea, Queen Ursula wont meddle in the rule of her stubborn triplet sons who, instead of ruling, lavish the riches of Viz on futile matters. Will the party guy (King Benjamin), the garden lover (King Bernard), and the control freak (King Bruno) ever get serious, especially as their smart/dreadful sister Princess Experalda, left out of royal ruling, aspires to their throne as king? Their incessant weird behaviour will only stop once the lost Dream Sofa is brought back to Viz through the help of the Bearer, the only one capable of reading the Book of Prophecies. Only he can guide them to its whereaboutsbut how will they find him?
