Bikini Horrors is a fan-made mod for Friday Night Funkin', built around a twisted, parody version of Bikini Bottom. It borrows the rhythm-battle format that made FNF popular and reskins it with SpongeBob characters, horror-tinged visuals, and parody tracks inspired by mods like Sonic.EXE, Sonic Legacy, Mario's Madness and Hypno's Lullaby.
The mod is the work of solo creator ChezzarCat, and has gone through several major versions — most recently V3, subtitled "Fiesta en la Piscina" (Spanish for "Pool Party"), which expanded the mod to 45 tracks. V3 is built on the Codename Engine.
| Creator | ChezzarCat |
| Latest version | V3 — "Fiesta en la Piscina" |
| Engine | Codename Engine |
| Total tracks | 45 (V1 + V2 + V3) |
| Main characters | 10+ (see full cast) |
| Setting | A parody of Bikini Bottom |
| Platform | Windows (Mac varies by build) |
The mod that started it all — introduced Spongephanes and the core cast in a smaller, horror-house setting with 6 tracks.
A contained horror-house take on Bikini Bottom. Establishes Spongephanes, SpongeWarrior, and the core horror-parody tone.
Guater Game — the opener, Spongephanes challenges SpongeWarrior.
F is for Fevil — Spongelord's moody, slower track.
Infinete — shifting time signatures, Kenny-brothers running joke.
Sunderwater — introduces Spongebud Squareguy mid-song.
Catch and Fish — deeper waters, Jose Juan.
Bubbletwister — Bob el Triste's emotional ballad.
View full tracklist →Bubbletwister closes V1 on a character moment for Bob el Triste and plants the deal with Spongelord that pays off much later in V3.
Built out the roster introduced in V1 with additional parody tracks and refined the existing horror-house stages.
V2 expanded the mod's song library and roster, giving returning characters more stage time while the horror-house presentation was tightened up.
V2's tracks are harder to pin down than the V1 and V3 sets — different community sources list different selections. The Funkipedia Mods reference page maintains the most complete list, and confirmed tracks are tracked on the songs database.
The pool party arc represents the biggest tonal and narrative shift. On the surface, the setting brightens into a pool party framing, but underneath it layers in pirate subplots, hallucination sequences, and revenge-driven storylines.
Vash a Morir — pirate opener tied to a cursed DVD discovery.
PARACETAMOL — restaurant hallucination with shifting tempo.
Ups, Me Caigo! — doll-themed encounter.
Rent Due — revenge storyline, the mod's longest track at 5:33.
Rumbeling — formula-chase storyline with frequent BPM shifts.
Powerscaling — Mermaid Bob, fast-scrolling chart.
Barnacles! — gacha-style cold open, novelty tribute.
For You, Someday — story ballad, no character icons.
Mr. Ketchup (Bob), Mermaid Bob, Barnacles Guy — fresh faces alongside reworked versions of fan-favorites.
Pirate subplot, hallucination sequences, and dialogue scenes that connect the new content back to V1 and V2 — including the payoff for Bob el Triste's V1 bargain.
Built on the Codename Engine, the modern FNF engine used by most current FNF mods.
The mod's antagonist and host of the party — a self-styled "underwater god" version of SpongeBob who opens the mod by challenging SpongeWarrior to his "underwater game." Treats every confrontation as a performance.
The hero figure the story's prophecy points to as the one meant to stop Spongephanes — effectively the mod's version of the player-aligned protagonist in its earliest encounters.
A moodier, more menacing figure tied to the track "F is for Fevil." Functions partly as a teaser for a separate, related mod project by the same composer.
Introduced mid-song in "Sunderwater," confronting a character called Squidwirdy. One of the more unsettling reveals in the early tracklist.
A twisted take on Squidward, on the receiving end of Spongebud's confrontation in "Sunderwater" — plays a mostly reactive, dread-filled role in that encounter.
One of Spongephanes' closest allies, encountered by the player characters during "Catch and Fish" while exploring deeper waters near Galicia.
A grief-driven character central to "Bubbletwister," searching for a lost love after making a deal to enter what the mod calls "Underguater Limbo."
A corrupted transformation appearing in the V3 track "PARACETAMOL," triggered by a hallucination-inducing condiment incident at a restaurant run by a Krabs-like boss character.
A superhero-parody transformation in the V3 track "Powerscaling," riffing on the Mermaid Man & Barnacle Boy segments from the original SpongeBob show.

The mod was created by ChezzarCat, a solo developer who handles composition, coding, character design, and stage art.
No — Bikini Horrors is a standalone parody that uses SpongeBob-inspired characters and settings but isn't connected to the official SpongeBob SquarePants canon.
The main cast includes 10+ characters tied to released songs. The full roster keeps growing with each update.
It's Spanish for "pool party," which frames the V3 arc. The title reflects the brighter surface setting of V3, though the underlying story adds darker pirate, hallucination, and revenge subplots.
It leans more into unsettling horror-parody than genuine terror. The comedy and self-aware tone keep it from being genuinely frightening. Think "weird and off-kilter" rather than "jump-scare horror."
