"Fire Pesh" is a painting by Mallory that she painted on a 7-hour art stream with Hayley in December 2016, after they finished recording Super Mario 3D World the night before. It was originally titled "Fire Pehsh", but auctioned as "Fire Pesh".
It is based on the character she played in her Let's Play of Super Mario 3D World with Stephen, Alex, and Hayley. Its style is inspired by a print of Marie Taglioni in La Sylphide, made by Alfred Edward Chalon.
It was released for auction at the end of the Super Mario 3D World Let's Play, along with a new shirt design inspired by the Let's Play.
