This is a sequel to Rock-a-doodle with a heroic owl named Osvaldo, who has to teach the grand duke how to protect the forest from a bunch of villainous rats, restore the good rat king named Ragu to the throne, and restore the musical mornings with the power of harmony
Note: the owl named Osvaldo, is based on Owliver from Annabelle's wish and Prof. Owl from Adventures in music-toot, whistle, toot and boom
