The protagonist must read the sign in the Art Club room when the computer's clock is set for October 10th at 8 PM (i.e. between 8:00 and 8:59) to encounter him, or all day on the Nintendo Switch version. The Muffet encounter must also be finished before the encounter in versions 1.00 and 1.001.
So Sorry's body is primarily orange, with brown accents and light brown hair. In battle, he can wear one of five different hats. The shape of his muzzle changes with his expressions.
So Sorry is an apprehensive, apologetic, but otherwise friendly artist. His attacks are not deliberate attempts to hurt the protagonist, but rather clumsy attempts to show his art and creativity.
- He swings his tail at the protagonist while he turns around to search for things in his vest. This tail uses blue and orange attacks.
- Crumpled paper is thrown at the protagonist in mass amounts.
- He mistakenly draws Doodlebogs, which throw doodles in circular formations at the protagonist. The Doodlebogs are disposed of with the "Draw" ACT option.
- When the battle is about to end, So Sorry does both of his first aforementioned attacks at the same time.
So Sorry cannot be spared. The battle can be ended in two ways.
- Progressing the battle without attacking for at least ten turns. The battle does not progress while Doodlebogs are present.
- Attacking 11 times.
- Before Battle

- Oh, I'm so sorry! How clumsy of me... I've bumped into you I'm such a klutz. I was just here to find something to draw, and... Oh no, it's ok! It's OK! I'll give you a gift to make up for your troubles. Let me look in my vest! [#1]
- Ummm, I couldn't find anything I want to give away. Wait, wait! I've got my notebook! I can draw you a picture in it! I'm quite the artist, you know. I'll draw you a GREAT picture!!! [#2]
- S... sorry... The drawing didn't come out very well. Wait! I know the problem! I just have to find a better piece of paper for it! [#3]
- None of my papers are good enough to use... IT'S OK!!! I know what I can do!! I'll use my magic pencil! It has to be under some of these papers somewhere!!!! [#4]
- Here! I got it! My magic pencil is amazing! Everything I draw with it looks... COMPLETELY REAL! Uuuuhhhh, oh no!! That's a little too real! [#5]
- AHHHHH!!! [#6, while any Doodlebogs are present]
- I've messed up. I've really messed up. Oh no. I'll just use a regular pencil! I'll try my best! [#7]
- Are you ready!? I just finished! Here's your picture! What do you think!? It's a representation of your deepest essence... It's great, right!? ... (They think my art is terrible.) Well! I'll leave you with that thought! Goodbye! See you later! Sayonara! Nice knowing ya! Hasta la vista. ... I should leave. [#8]

- Oh! Whoops! That hurt! So sorry, I must have gotten in the way! I really shouldn't stand so close Ah I'm just being troublesome. [#1]
- Darn it, I keep getting in the way So sorry, I'm such an oaf Wandering in front of you... [#2]
- ... Are you... trying to KILL me? ...so sorry, but I've had a really tough year. I don't know if I could take you killing me on top of everything. You should find someone else to kill. So sorry. [#3]
- ????? I just said I'm not interested in the offer!! ... Sorry, I must not have enunciated clearly enough. I am not interested in being killed. Thank you very much. [#4]
- Look, stranger I... I guess I'm going to have to tell the truth. My whole life, I've never been worth a lot of EXP. Everyone else at my work, in my classes, Would raise a person's LV by 4 or 5 when destroyed... But me? I wouldn't even increase your LV by 1. For this reason... I... I've always been... I've never been very good at getting killed. So... I'm flattered that you... Want to destroy me. But you are making a big waste of your time!! Stop killing me!!! [#5]
- OK, OK. Hm. ... If you stop killing me, I'll pay you 200G. [#6]
- 220G? [#7]
- ... 300G? [#8]
- W... Wait a second. You're trying to kill me... C... could it be...? Because you don't like me very much...? No, no, that can't be! This is just a friendly, um, killing between acquaintances!!! Pals... we're... we're still pals, right!! OK, maybe not PALS, but, uh, Friendly strangers? You know, just one step away from being buds!! I mean, I was practically... I was about to crack open the sparkling cider! Pull out some baguettes and some swiss cheese! BLOW ON A FREAKING PARTY HORN!!! [#9]
- N... no, you don't like me either, huh...? Nobody likes me... they're just putting up with me I'm just annoying you... I should leave ARRRRRGHHHH!!! Why am I such an idiot??!?!!!! How did I not see it before!!! You weren't killing me because you LIKED me!!! NOBODY does that! That's NOT a thing! [#10]
- Oh. Sorry. I was being too loud. Ugh. I'm wasting your time, aren't I...? ... ...whew, I feel really... strange. I think I need to go home and lie down. Oh, and... About all this. Um. Sorry. [#11]

- So Sorry has five different hats that he might wear in battle: a party hat, a tiny cowboy hat, a beret, a jester hat, and a fedora.
- So Sorry and Asgore are the only characters to use both blue and orange attacks (not including the lasers in Hotland and the CORE.)
- So Sorry cannot be encountered in the Genocide Route as floor 2 of Hotland (where the Art Club Room is located) is blocked off.
- If Art Club Room is entered on the Genocide Route, So Sorry still cannot be encountered as the sign in the Art Club Room reads "(Art club is cancelled!)."
- His appearance is partly based on the backer's own pre-existing avatar. The backer, Samael, wanted to minimalize his own appearance and personality from his in-game representation to give Toby Fox more room to design the character more spontaneously.
- Temmie Chang made a front overworld sprite for So Sorry, but it was not used and So Sorry is only seen from the back outside of battle. However on the Nintendo Switch version, So Sorry's front overworld sprite can be seen in the True Pacifist Route, but only after facing him. He can be seen standing outside the Art Club Room opposite from Tsunderplane.
- Like some other characters in the game, So Sorry's flavor text pronouns contradict each other, giving the terms "it," "they," and "his."
- If So Sorry is spared after the sixth, seventh, or eighth time he is attacked, the GOLD gained from sparing him afterward is increased depending on the last amount of GOLD he offered to stop killing him. However, on the eighth time he is attacked, 318G was earned instead of the 300G he offered. The reason for the extra 18G is currently unknown.
- So Sorry's original creator, an artist known as "Samael," was the subject of harassment after his character was discovered because of the fat fetishism themes in his work.
- So Sorry's name most likely comes from the fact that he never mentions his name. One of his first lines spoken to the player is "I'm so sorry!". The "I'm" could be interpreted as "My name is."
- When So Sorry's HP has been depleted, he tries to limp off-screen like Sans. However, he dies before doing so.
- After killing So Sorry, the sign in the Art Club Room reads "(Art is dead.)."
- "Today's the day you can go to the Art Club on Hotland 2F and have a special meeting. That's 8PM (your time). On the Switch version you can meet all day though!!" - Toby Fox. October 10, 2018. Twitter
- "So, Toby asked me if I’d be cool obscuring the connection since the character is a pre-existing thing. Part of its so the game feels like a self contained unit and give him control as a creator, which I totally get and I was fine with, and part of it was to avoid the issue of people seeing the name, googling it and giving me stick." - Samael. October 23, 2015. Tumblr.
- "In the end, we didn’t even get to see the lovely sprite Tuyo did for So Sorry’s front - we only get the back in the game." - Samael. April 21, 2016. Tumblr.
