Undertale – So Sorry is a secret miniboss. You can only meet him if you fulfill a certain condition. To do this, you need to go to the art club at a certain time. There you need to read the tablet, and then you are able to get acquainted with this very modest and insecure artist.
Well, what will eventually happen to him after your battle depends on which path you are following: pacifist, genocide or neutral. It is worth noting that one of his advantages is the fact that he has five different hats. And just the same, during the battle with him, you can see the random one.
In addition, since this opponent is quite creative, then his attacks are like that. Therefore, fight off the doodles that will sometimes appear on the screen and try to attack you. Therefore, it is possible for you to find other secret characters like him.
