Friday Night Funkin: In a Wimpy Day is a fan-made Friday Night Funkin mod inspired by Diary of a Wimpy Kid, the popular book and film series about Greg Heffley. The Wimpy track, credited to Cótiles, is one of its short original songs, built around bright electronic melodies that suit the mod's cartoon school setting. Clips from the mod have circulated among FNF players and Wimpy Kid fans on video platforms and soundboards, where short, recognisable songs are easy to reuse. Its cheerful, meme-friendly sound keeps it popular for edits and fan videos.
