The Fun Is Infinite meme originates from a hidden sound test screen in the 1993 game Sonic CD. By entering a specific code, players are greeted by an unsettling screen filled with human-faced Sonics and the message 'Fun is infinite with Sega Enterprises - Majin.' While Majin was actually a nickname for designer Masato Nishimura, the eerie music and distorted visuals caused many western players to view it as a creepy or cursed image. The meme saw a massive resurgence in recent years due to its inclusion in popular Friday Night Funkin' mods, where Majin Sonic was reimagined as a rhythmic antagonist, cementing its status as a staple of internet creepypasta culture and surreal humor.
