Three friends take turns choosing a colored box, with the goal of not choosing the wrong box. Each box contains a surprise challenge. The first friend chooses a yellow box and finds scissors, but is also given a challenge to cut their hair, which they reluctantly accept and end up cutting just a small amount. The second friend chooses a purple box and is given a blindfolded challenge to identify parts of the body by touch. The third friend chooses a blue box and finds a slime, which they have to touch and examine. After initially finding the slime to be dry and crusty, they are able to revive it by adding liquid and other ingredients, and then make bubbles with it.
