Ms. O tells a story about the hydraclops' attack on the Odd Squad headquarters. One of the agents finds out what each hydraclops dislikes and represents their dislikes in a venn diagram. Unfortunately, the team has only enough time to fire one shot at both hydraclops, so they will need to find something that both of them dislike. Ms. O explains venn diagrams to the team and uses one to find a mutual dislike: eggs yolks.
