Undertale is an indie role playing game released in 2015 and created by Toby Fox, known for its retro presentation, menu driven battles and distinctive 8 bit inspired sound design. Its short interface blips became as recognisable as its music, shared widely through fan games, remakes and video edits that copy the original menu style. The create effect survived that spread because players associate it with starting a new journey and making a first choice, so creators still use it whenever they want an instant Undertale reference without playing a full track.
