For an extra credit science project, Arthur builds an ant farm, but all the ants spill out of the ant farm and he must find a way to attract them back in. When Arthur accidentally destroys Francine's project while trying to catch the ants, they get a new idea and team up to work on the project together. Muffy starts an advice column, but one of the Tough Customers, Molly, turns out to be a better advice giver. Muffy tries to improve her column by copying Molly's appearance and interests.
