"'Heya there! Glad to see some new tourists here for the summer heat! If you happen to find any shells around I'd be willing to trade you some special, limited time items for them!'"

Overview
Andy is the man running the Summer Event Shop during the season of summer. He has many summer-related Event items in his shop, but also shares the same offers as Wandering Shopkeeper as well. Aside from having offers that change every day, he also has a Shell Exchange where you can exchange shells for offers that don't change for the duration of the event.
