The Nice Cream Guy is an optimistic individual, who despite the lack of customers, keeps searching for business opportunities somewhere else. Before the protagonist interacts with the Nice Cream Guy at Snowdin Forest and Waterfall, he has a downhearted expression, with closed eyes and ears drooping. However, he becomes very excited when the protagonist talks to him, and promptly offers them some Nice Cream. At Hotland, if the protagonist spares the Royal Guards, the Royal Guards buy all of his Nice Cream, which in turn, makes him content and hopeful about the future of his business.
