Sprunki Mustard

What Is Sprunki Mustard?

Sprunki Mustard is a fan-made recolor mod built on top of the Sprunki universe, itself an unofficial fan project inspired by the browser music game Incredibox. According to the Sprunki mod Wiki on Fandom, the build most players know by this name is also called Sprunkstard — its Cocrea uploads usually carry the subtitle "If Sprunki Were in Mustard" — and the wiki documents it as the first Sprunki reskin ever made. The same entry states emphatically that the mod is not supported by NyankoBFLol — the fan creator behind the original Sprunki — placing Sprunki Mustard firmly in unofficial fan territory rather than an authorized spinoff.

The mustard concept did not start with Sprunki. According to its itch.io listing, it traces back to Colorbox Mustard, a parody mod credited to creator slapbread and a six-person team working under the name Superbanger Productions, itself a parody take on the Colorbox series by Baggerhead. That project went up on Cocrea on August 29, 2024, before being mirrored to itch.io as both a browser build and a downloadable Windows version, and its listing states outright that it is "Not affiliated with Sprunki." The connection came later, when fan modders lifted that mustard-yellow visual treatment and applied it to Sprunki's own cast, giving rise to the Sprunkstard reskin and the wider "Sprunki Mustard" family of pages found across fan sites today.

Because Sprunkstard spread mainly through Cocrea, a Scratch-compatible remix platform, no single build is the definitive version. Multiple creators have re-uploaded their own copies under the same "Incredibox Sprunkstard [If Sprunki Were in Mustard]" title, each with small differences. That's why "Sprunki Mustard" isn't one centrally maintained release — it's closer to a shared fan concept than a single fixed game.

How to Play

Sprunki Mustard follows the same drag-and-drop mixing format used across the Sprunki family and the Incredibox games it descends from. Rather than following a script, you build a track piece by piece by placing characters on the stage, each one adding its own sound layer.

• Drag a character from the selection roster onto the stage to add its sound to the mix.
• Combine beats, effects, melodies, and vocals to build out a full track.
• Remove or mute a character if the mix starts to feel too busy, then bring it back later.
• Swap characters one at a time so you can hear exactly how the mustard-reworked sound set changes the track.
• Let a combination loop for a few bars before judging it, since some sound layers only reveal their full effect after repeating.

What's Different in Mustard

The defining trait of Sprunki Mustard is visual: characters and much of the interface are recolored into a mustard-yellow palette, replacing the varied designs of the base Sprunki roster. Fan write-ups describe the effect as a "haunting, monochromatic twist" on familiar character art, with the yellow tint applied consistently across characters and backdrop rather than as a one-off skin on a single figure.

The mustard treatment brings its own sound set along with the recoloring, layered onto the drag-and-drop structure the wider Sprunki series already uses. Some fan documentation also ties a mustard-yellow character named Mard to this branch of the series — described on the Incredibox Sprunki Wiki as wearing an olive-green visor and a bandana reading "I love mustard," and loosely connected to broader Sprunki fan lore. How closely any single build follows that description varies by upload, since, as noted above, the mod exists as multiple independently maintained copies rather than one fixed release.

To compare the mustard-yellow idea across its fan branches, related pages worth checking include Incredibox Mustard, Mustard Sprunki, and Incredibox Sprunkstard, along with two further remix branches, Sprunki Version Mostard Remix and Mostard Remix Remix — each a separately uploaded take on the same concept.

Tips for New Players

• Start with two or three characters before layering in more so you can hear each one's role.
• Mute anything too chaotic, then reintroduce characters one at a time.
• If you already know the base cast from the original Incredibox Sprunki, listen for how the mustard reskin changes sounds you recognize instead of learning a whole new roster at once.
• Because different creators host their own Sprunkstard copies, character names and sounds can vary slightly between builds.
• New to the series? Trying an earlier entry like Sprunki Phase 1 first makes it easier to spot what the mustard treatment changes.

Frequently Asked Questions

Is Sprunki Mustard free to play?

Yes. Sprunki Mustard is free to play in your browser, with no download or account required.

Is it official Incredibox?

No. It is a fan-made project several layers removed from Incredibox: the underlying Sprunki series is an unofficial fan mod, and the Sprunki mod Wiki states that Sprunkstard, the mustard reskin, is not supported by NyankoBFLol, the fan creator behind Sprunki. The mustard-yellow visual style itself began with the unrelated Colorbox Mustard parody mod before being adapted onto Sprunki's cast.

What's the difference between Sprunki Mustard, Sprunkstard, and Colorbox Mustard?

Colorbox Mustard came first, as a standalone parody of the Colorbox series with its own cast, and its listing is explicit that it is not affiliated with Sprunki. Sprunkstard is the mod that took that mustard-yellow treatment and reskinned it onto Sprunki's characters instead — fan documentation credits it as the first Sprunki reskin of its kind. "Sprunki Mustard" is the umbrella name fans use for that Sprunki-side reskin, though because it spread through independent Cocrea reuploads, several versions exist across fan sites with small differences.

Can I play Sprunki Mustard on mobile?

Yes, it runs in modern mobile and desktop browsers, though a larger screen makes the roster easier to manage with precise drag-and-drop.

Where can I find other Sprunki variants?

If mustard isn't the version you're after, the wider Sprunki family includes darker takes like Sprunki Retake, fan-made pages such as Sprunki OC, and the numbered entries on the Sprunki phases hub.
