Sprunki began as a fan made Scratch project inspired by Incredibox and quickly spread online through remixes, phases and character specific treatments shared by its community. This Simon and Wenda version comes from a Scratch treatment project that reworks how the two characters sound together, rather than using their default loops unchanged. Simon is the yellow melodic character and Wenda is the white vocal character, and pairing them became popular in fan mixes and short videos. Treatment remixes like this one keep circulating because creators enjoy comparing each new mix with the original.
