Oobi is outside, hiding something in a blue box. He sees Kako walking by and gets the idea to play a guessing game. Oobi tells Kako that there's an animal inside the box and asks him to guess what it is. He gives him three clues: legs, green, and tail.
Kako is puzzled and can't figure it out. He guesses a cat, a frog, and a parrot, then imitates each one. Oobi gives him a fourth clue: shell. Kako thinks for a second and guesses that it's a monster. He pretends to be a monster by saying "bleh!" and sprawling his fingers out. Oobi laughs, then asks him to think harder. Kako realizes it must be a turtle. Oobi lifts the box, uncovering the turtle. They play with the turtle as the short ends.
