Yumbobo is a new ice cream shop in Elwood City, across the block from the Powers family's Ice Cream Shop. It has whimsical flavor names, futuristic furniture, and a cute mascot named Puk Puk. They grew so popular that Brain was terrified that they would put the Ice Cream Shop out of business, so he began adding incentives to lure people back to his store. It is possible Yumbobo has gone out of business.
