On August 5, 2020, the Toadstool Shadow Coloring Contest began. Original line drawings by Toadstool Shadow graphic artist Arielle Johnson were put up on Instagram and Facebook. Everybody who colored one in and posted it to their social media with an @toadstoolshadow handle got a 25% discount coupon code on the Rainbow Nights album on Bandcamp. Judged on the full moon of September 1, 2020, the grand prize winner, Angel Hernandez, of San Miguel de Allende, Mexico, won a free Toadstool Shadow elfcore t-shirt.
