Oobi is playing with his favorite toy car when notices that one of its wheels is squeaking. At first, he seems not to be bothered by it. Grampu walks in with a toolbox and asks Oobi to help him fix the sink. Oobi agrees and Uma comes in asking if she can play with his car while he's helping Grampu. He says yes, but tells Uma to be especially careful with the toy. Uma plays with the car and notices its squeaky wheel. She accidentally lifts the car onto its side, breaking one wheel off. Uma is distraught and attempts to repair the toy before Oobi notices. She uses toy tools to fix it and inadvertently breaks both the door and the engine cover off. Oobi walks in and asks where his car is.
Uma tries to hide the broken car, but Oobi sees it anyway. After realizing what has happened, Oobi is furious and shouts at Uma for not being careful. Grampu comes in to check on the children and explains to Oobi that Uma made a simple mistake. Oobi forgives her and asks Grampu if he can fix his car. He brings his toolbox out and fixes the car within minutes. Oobi tests it, only to find that its wheels are still squeaky. Uma helps by applying oil to the wheels, fixing the problem. Oobi thanks Uma and plays a remember game with his car, a firetruck, and a bus. Uma then rides the firetruck away as the episode ends.
