"Uma Bathroom!" is an episode of Oobi from the first season.
After an enjoyable day of playing with Oobi and Kako in the mud, Uma objects to taking a bath. She soon learns that bath time can be fun when you add a dance game to bathroom activities. — ABC Television
Uma is walking along when she sees a pile of mud in the garden. She proceeds to make a mess with the mud, covering Oobi and Kako with it in the process. When the children walk inside, Grampu gives the boys a bath. He offers to give Uma one as well, but Uma refuses to step inside the bathtub. Uma attempts to convince Grampu that she is clean by wearing a towel. Grampu pulls the towel off, revealing that she is still covered in mud. This prompts Uma to run away as Grampu chases her, laughing.
Uma agrees to enter the bathroom and tries to stall by using the toilet and washing in the sink. She sees herself in the mirror and pretends that she is a monster. After this, she is told to get in the bath again. Uma is hesitant, but decides that it must be done. She climbs into the tub and sings a song about bath time. When she finishes washing up, Grampu is relieved that Uma is clean. However, he notices a trail of mud-covered handprints on the bathroom wall. He sighs and begins to clean them up.
The next scene shows Uma playing a bath-themed dance game. She teaches the viewers three moves: flushing the toilet, washing up, and drying off. Uma is interrupted prematurely by Oobi, who explains that he needs to use the bathroom. Oobi says "goodbye" to the viewers as the episode ends.
