Epicircles are a type of cereal. They were created by Mr. Epic and endorsed by Bob. Bob eventually bought half the shares. The Epicircles brand is very successful. They sell more boxes each year than the year prior.
They are actually quite nutritional and the box art saying "The Most EPIC Cereal" draws people in. They are slowly taking customers from Soggy Oat Nuts which are not nearly as epic. However, the percenatge is very small and it will take until 2590 before people stop buying from them.
