Flavor text when encountering So Sorry
Wrong Enemy !? is the 60th track in the Undertale Soundtrack. This song plays when fighting the hidden mini-boss So Sorry, who only appears at Hotland on October 10th at 8PM (all day on the Nintendo Switch port) It has the same soundfont as the Wrong Number Song. This, along with the fact that the caller is "very very sorry" may imply the caller to be So Sorry.
