Preteen Moochie Daniels only wants a dog, but his father Daniel is allergic to canines, such as his neighbor Charlie Mulvihill's rundown shepherd dog Bundles, who secretly trains his pet to help him steal jewelry. Mucky's brother Wilbert "Wilby" is intelligent and shy, a promising inventor, but he is hopelessly clumsy in the girl aspect. He envies his smooth partner Trey, who has no problems. Desperate Wilby sought help from the spell of the Lucrezia Borgia ring (he unexpectedly obtained it from his father's antique museum), which miraculously transformed him into Bundles and brought him back when he couldn't control it. That's why he also knew that the diamond borrowed from his father's museum was Charlie's next goal, but who would believe his story?
