About Barnacles!
Overview
Barnacles! is a V3 track composed by Willart-Mei, and its runtime is still pending confirmation. The song is documented as a novelty tribute — and it's unapologetically goofy compared with the rest of the V3 set. Where PARACETAMOL goes for chaotic atmosphere and Bubbletwister went for emotional weight, Barnacles! leans fully into comedy and parody.
The tribute framing is the key: the track is built around Shucks, described as the opposite of Barnacles Guy. That push-and-pull between the two characters is the engine of the gag — a song that keeps threatening to be a straightforward tribute before being cut off by its own premise.
The Gacha-style cold open
The most distinctive thing about Barnacles! is how it begins. It opens in a deliberately low-budget "Gacha Life"-style animation — a stylistic joke that instantly separates it from the rest of the OST, which generally presents with more polished production. The rough, meme-adjacent presentation is the setup: the audience expects a gag track, and the gag arrives exactly as promised.
Into that opening steps a crossover cameo: Sans. The Undertale character gets a short-lived playable cameo here before being taken out by Barnacles Guy. It's a blink-and-you'll-miss-it appearance in terms of the song's runtime, but it's exactly the kind of fan-crossover moment that makes novelty tracks memorable — and it's one of the few places the mod steps outside its own cast.
Story role
Barnacles! doesn't advance the revenge, pirate, or hallucination storylines of V3. Its role in the tracklist is comic relief with a structural twist: Barnacles Guy brings the track to a sudden, gacha-style end, cutting the song off rather than letting it run to a natural close. That abrupt ending is the punchline — and it makes the track one of the most easily recognizable songs in the mod by shape alone.
Notes for players
Because Barnacles!' runtime is still TBC, it's kept out of the soundtrack's length-based groupings on the song database page. In practice the track's full experience depends on the visual gags — the cold open and the sudden ending — which makes it a song better appreciated in gameplay than as a standalone listen.
