This piece is more of simple doodles. It is part of the open drawing community drawing board on Pixiv. On the bottom right, the simple colored swimming Fuku, flame - Papyrus, Sans, Chara and Frisk are my contribution, along with the sitting Frisk with Flowey just above. A fellow regular artist named 苔次郎 was getting troubled and depressed over Chara's fate, and drew a dejected Chara on the bottom left in red ink. So, in return, I drew Toriel and Asgore in the blue ink. 苔次郎 quickly drew Chara running into Toriel's arms.

Oh, yes. Earlier in the session, I did manage to quickly doodle the young Flame family. It is the simple colored piece in the center of the picture.
