Sprunki is a fan-made music game inspired by Incredibox, in which players mix loops from colourful cartoon characters to build a track. Its horror mode became a viral favourite online because it flips those cheerful characters into corrupted, unsettling versions, and creators began sharing the transformed sounds as short clips for edits and reaction videos. Simon is one of the original characters in that cast, and his Parodybox horror version is popular with fans who want a recognisable voice turned creepy without using a full song.
