Oobi is in the kitchen, eating a bowl of cereal called "Toasty Chunks." He sings the cereal's jingle before being interrupted by Grampu, who is about to take Oobi to his pediatrician's office. Oobi is nervous at first and asks if he is sick. Grampu assures him that he is not sick and that it is simply a routine checkup. The pair arrives in the waiting room, where Oobi sees a bead maze toy. He plays with it for a while before a young boy named Chauncy appears. Chauncy has just met the pediatrician, Dr. Rose. He tells Oobi that she is friendly.
Dr. Rose greets Oobi shortly afterwards and invites him into her office. Oobi admires the colorful walls, which are decorated with images of sea creatures. Dr. Rose asks Oobi about his diet. He tells her about his favorite foods, which include pizza and cake. The doctor tells him that those foods should only be consumed in moderation. Dr. Rose later asks about Oobi's siblings and tells him that she has a brother of her own. The next scene is an interview segment in which Uma pretends to be a doctor and asks preschoolers about their doctors.
The scene cuts to Oobi, who is being weighed by Dr. Rose. Afterwards, Dr. Rose checks Oobi's eyes and ears. Finally, Dr. Rose must give him a shot. Naturally, Oobi is afraid at first. He decides to be brave and take it. After the shot is over, Oobi asks when it will start. Grampu explains that he did not even feel it, and that the checkup is over. Oobi says "goodbye" to Dr. Rose and to the viewers as the episode ends.
