Deltarune is an indie role-playing game created by Toby Fox as a follow-up to Undertale, with its first chapter released in 2018. Hidden phone interactions and other small secrets have become a favourite talking point among players, who share discoveries in clips, streams and fan edits. This six-second entry, catalogued online as Entry Number 17, circulates in that fan culture as a shorthand for a found secret. It remains useful because Deltarune fans instantly recognise the reference, while the phone-cue format also works in unrelated edits about calls, messages and surprises.
O tym dźwięku
A short phone Easter egg sound from Deltarune, used by fans and editors online for secret-call jokes, hidden-detail reveals and playful game edits.
This short clip captures a hidden phone moment from Deltarune, presented as a compact six-second cue that feels like a secret tucked inside the game rather than a normal menu sound. It has the crisp, electronic character of a phone interaction, with a light, slightly mischievous tone that stands out against the game's usual adventure music. For listeners who know Deltarune, it lands as an inside joke and a small discovery, sparking recognition and curiosity, while for newcomers it still works as a quirky, attention-grabbing alert that suggests something unexpected is about to happen.
