Oobi and Uma are in their room, preparing to go to sleep. Oobi helps Uma put her barrette away for the night. Grampu walks in and tucks the two children in. He is about to turn off the lights when Uma asks him to sing her a lullaby. After he sings her the "Uma Sleep" song, Uma invites the viewers to sing along. Following another verse, Uma falls asleep and Grampu turns off the lights.
The next scene shows Uma's dream. It takes place in a purple-colored world. Uma sees a strange tree and a large animal approaching. She is shocked and immediately wakes up, calling for Grampu. Grampu rushes to Uma and turns the lights on again. He asks her what happened and she explains what happened in her dream. Grampu tells her that dreams are just figments of her imagination. He tries to turn the lights off, but Uma asks him for a cup of water. She then asks to go to the bathroom, just to stall for time. The next scene shows Kako interviewing preschoolers about their dreams.
After this, Uma is shown walking back to bed. Oobi can be heard mumbling "Oobi, you, friends" in his sleep. Grampu laughs and tries to get Uma to fall asleep again. She tells him that she is too afraid, so Grampu asks the viewers to show Uma how to relax and breathe deep. He then tells Uma to think good thoughts. She decides to think about Oobi, Kako, and chickens. This gives her the courage to fall back asleep. She starts dreaming again and appears in the same purple world. The same tree and animal appear. A lamp's pull chain appears from the sky and Uma is prompted to tug on it. After she does this, the animal becomes a chicken and the tree starts to dance. Uma laughs and pretends to be a chicken herself.
Uma wakes up the next morning, ecstatic to have turned her nightmare into a "silly dream." She rushes downstairs to tell Oobi and Grampu, who are eating breakfast. She shows them her chicken dance and invites the viewers to dance along. The episode ends as Oobi waves "goodbye."
