The Rise of the Cheese Haters was a horrible event that surged forward out of hatred of cheese that led to the formation of the Cheese Haters. Peachycakes is known to be the leader, and Sherrif Jorge, Officer Knife and Deputy Wayoshi are suspected to be members. When the Cheese Lovers found out about them, they started a war. The Cheese Lovers had more members, but the Haters had stronger people in them. It was a close battle, but in the end, the Lovers lost, ending the Cheese Craze of '07. However, they were sent to prison on the Moon, where they decided to stay because of the green cheese after they took over. Nowadays there isn't much of a grudge between the opposing groups because several Haters have defected. Evil Guy destroyed the Haters once and for all by defeating their leader after she took over the Cheese Lovers' base.
