In 2023 I combined two prompt lists because one list I was really interested in had only prompts for half the month (so artists had two days to complete a piece for each prompt, basically). So I combined that list with Rattober that year! I also alternated between digital and traditional media, usually doing Rattober-only days in traditional media until near the end of the month.

It's several comments on this piece that first introduced me to Geronimo Stilton. Whom I still don't know much about, except that character very much fits the prompt of "bookworm rat" as well.
