Tunner comes from Sprunki, a fan-made music game inspired by Incredibox in which players place characters on screen to build layered songs. Each character contributes a short repeating loop, and Tunner's normal mode version is his standard, non-horror sound, heard before the game's darker alternate mode changes the characters. Clips of individual Sprunki sounds spread widely on YouTube, TikTok and soundboard sites as fans shared favourite characters, recreated mixes and compared normal and horror versions. Tunner remains popular because his steady loop works as a reliable base for new arrangements.
