Oobi is dancing to classical music when Uma tells him that it is time to attend dance class. They walk to a dance studio, where they greet their teacher, Tulla. Tulla tells them that they will practice a special dance consisting of 3 moves: jumping, wiggling, and turning. He tells them that they will perform it at an upcoming dance party. Oobi and Uma enter separate rooms to practice. In Oobi's practice room, Oobi seems to understand the dance on the first try. Grampu walks in and tells Oobi to add more wiggle. They wiggle until Oobi accidentally knocks Grampu down wiggling, but he gets up and compliments him on his wiggling.
Meanwhile, in Uma's practice room, she is having trouble remembering the last move. Tulla walks in and reminds her to turn around gracefully. She does this correctly as Oobi comes in, still wiggling. He keeps going until Uma gets his attention. Tulla asks Oobi and Uma to dance together. After they finish, Tulla announces that it is time for the dance party. Grampu flips a light switch, which causes a disco ball to appear. Disco music begins playing as the characters do their dance and ask the viewers to do the same. They then decide to display freestyle dance moves as well, as a rock song plays. Kako then asks the viewers if they like to dance, followed by a montage of kids dancing.
When Oobi and Uma arrive home again, they decide to play a stop/go game in which Oobi plays music and Uma dances. When Oobi stops the music, Uma and the viewers are instructed to stop dancing. Grampu walks in and wants to play as well, and the kids are hesitant at first, but they let him do it anyway. He brings out a stereo boombox, which is much larger than the toy cassette recorder that the children were using previously. They dance to Grampu's music as the episode ends.
