Oobi and Uma are at the park. A woodpecker is drilling into a tree, Oobi is playing with his toy car, and Uma is playing paddleball. Uma spots Frieda nearby and tells Oobi to visit her. Oobi invites the viewers to call Frieda with him. Frieda greets Oobi and asks him to play with her and another puppet named Frankie. Oobi is surprised to see that both Frieda and Frankie are foot puppets, as opposed to hand puppets.
Frieda and Frankie decide to play a variation of the children's game "This Little Piggy," in which they point to each other's toes and pretend that they are pigs. Oobi thinks that he cannot play. Frieda helps him realize that although he is not a foot, he can simply use his fingers as "piggies." After they end the game, Oobi asks to play "hand clap." Frieda and Frankie decline and play dress-up instead. They do this by wearing shoes. Oobi tries to wear a shoe as well, but is unable to. He sighs as an interview segment begins. It features preschoolers talking about their best friends.
After this segment finishes, Frieda and Frankie play kickball. Oobi is frustrated when he cannot kick the ball and decides to leave. He talks to Uma about his predicament. She laughs hysterically upon hearing that he will not play with Frieda just because he is different. She points out things that they have in common, such as their ages and sense of humor. Uma suggests giving each other piggyback rides. Uma hops on Frankie's back and Oobi hops on Frieda's. The episode ends as Oobi waves "goodbye" to the viewers.
