An All-New Web Comic Strip by Andrew K Schirripa is in the works about day-to-day life seen through the eyes of a small sentient mushroom. Comics will be posted to Tapas and Webtoon Irregularly.
The Mushroom Skull was originally featured in an unfinished Rin's Comet chapter explaining the evolution of the Obsidian. This creature was eventually chosen to be the mascot of Mushroom World Comics, and also to be the star of its very own Web Comic.
