After settling down in Animal Village, Ai wastes no time and establishes herself as a self-sufficient young lady. As she acclimatizes to her fresh environment, she develops close relationships with the varied inhabitants of the village. While taking a leisurely walk on the shore one fine evening, Ai chanced upon an enigmatic note in a bottle that motivated her to set out on a venture to cultivate pine trees across the village, in hopes of creating an awe-inspiring impact on the approaching Winter Festival.
