Oobi is shown sleeping in his room. Toys and clothing can be seen scattered across the floor. Grampu walks in and tries to wake Oobi up. He is unable to do so by himself, so he asks the viewers to help wake Oobi up by calling his name. Oobi awakens and says "good morning" to Grampu. He looks out the window and admires the beautiful day. Oobi is about to play outside when Grampu stops him and explains that his room needs to be cleaned. Oobi looks at the mess and agrees that it needs to be picked up. Uma walks over, holding a feather duster. She shows Oobi that her side of the room is spotless and hands him the feather duster.
Grampu appears in an interview segment with a preschooler while Oobi begins cleaning up. Grampu talks about cleaning and dusting. The next scene shows Oobi organizing his toys, books, and socks into neat piles. He asks Uma to help, but she would rather play outside. Oobi then asks the viewers to help him put different items in each pile. He is interrupted by Kako, who wants to come over and play. Grampu tells Kako that Oobi needs to finish cleaning his room first. Kako accepts this and borrows a ball from Oobi's room.
Kako joins Uma outside, but the two of them are bored without Oobi. They plan to help Oobi clean his room and turn it into a musical game. They sing the "Clean Room" song as they clean together. When the song ends, they ask Grampu to inspect their job. He is impressed and tells the children to enjoy themselves outside. Oobi waves "goodbye" to the viewers as he runs to the backyard to play.
