Kako appears and explains to the viewer that he has scheduled a playdate with Oobi. He knocks on Oobi's door using a "secret knock" that he and Oobi came up with. He invites the viewer to use the secret knock as well. Afterwards, Oobi opens the door and exchanges a friendly handshake with Kako. The boys plan to play, draw, and sing. They are interrupted by Grampu, who calls from the kitchen. The boys rush over and find out that Grampu has bought a pet turtle for Oobi. Oobi is amazed by the turtle and cannot stop looking at it. Kako is visibly jealous and asks Oobi to play with him outside. Oobi accepts and takes the turtle with him.
In the backyard, Kako suggests playing a game of tag. Oobi declines and asks to play "turtle peekaboo" instead. He takes a flowerpot and places it on his head, pretending that it is a turtle shell. Kako reluctantly joins him, but ends up disliking the game. He asks Oobi to draw with him. Oobi tries to bring his turtle along, but Kako tells him not to. They go inside and set up an art easel. Oobi is still focusing on his turtle and asks if his turtle is okay. Kako dismissively tells him that the turtle is fine. He begins drawing a house, a sun, and a tree with multicolored markers. Oobi takes a green marker and draws a turtle. He laughs and walks outside to see the turtle again. Kako follows him and asks to sing with Oobi. Oobi begins and sings "green, shell, oh, turtle!"
Kako immediately gets furious and upset and explains that the turtle has become a problem. He storms off and tells Oobi to "enjoy" his turtle. Oobi realizes that he has hurt Kako's feelings and apologizes. He exchanges a handshake with Kako once again. Kako decides that it would be best to play with both Oobi and the turtle, so he starts another game of "turtle peekaboo."
Afterwards, Oobi appears in several interview segments asking preschoolers about their pets. Following this, Grampu and the boys play a letter game in which they find objects that begin with the letter "T." Oobi ends the game by saying "goodbye" to the viewers.
