"Haircut!" is an episode of Oobi from the first season.
Oobi wakes with a wild patch of hair. He first tries to hide it, then styles it, but nothing seems to satisfy him. Oobi asks Grampu to bring him to the barber, where Oobi gets his very first haircut. — ABC Television
Grampu walks into Oobi's room and wakes him up. Oobi stretches and looks at his reflection in the mirror. He notices that he has grown a head full of hair. He is embarrassed to show Uma when he walks downstairs, so he hides it under a flower. Uma is unaware of Oobi's hair until she asks him to smell the flower. She does this with Oobi's approval, only to ask if she can hold it, which Oobi approves as well. She ends up uncovering Oobi's hair, looking shocked at first, only to reveal she thinks it looks nice. Grampu tells him the same, but Oobi is not convinced.
Kako comes over, and Oobi shows him his hair. Kako suggests he puts hair gel in it and style it. First, he styles it up, but Oobi doesn't like it. Then he styles it down, but Oobi still doesn't like it. Oobi then gets the ides to get a haircut, and they call Grampu to take him to get one. They go to the local barbershop, where they see a woman shaking her hair back and forth. This inspires Oobi to do the same.
The barber asks Oobi what kind of haircut he wants. Oobi is afraid, for he has never gotten his hair cut before. Grampu offers to get a haircut first to show Oobi how painless it is. This gives Oobi the courage to get a haircut. The barber shows Oobi a list of styles to choose from, but he does not want any of them. Oobi explains that he wants Grampu's hair, meaning he wants bals hair. The scene cuts to a brief musical montage of Oobi's haircut. Once his haircut is complete, Oobi asks Grampu if he is still the same person now that he has lost his hair. Grampu laughs and assures him that he will always be Oobi.
In an interview segment, Kako asks the viewers what it is like for them to get a haircut. Afterwards, Oobi is seen in the living room wearing a wig. He gets the idea to play a dance game, in which he does the "Hair Dance". The three moves are: bounce, shake, and twirl/ He accidentally shakes it off of his head, and it falls onto Grampu as the episode ends.
