SPRUNKI / MUSTARD
What is Sprunki Mustard?
This player runs Incredibox Sprunkstard [If sprunki were in mustard], a mustard-themed Sprunki music mod. It shares the drag-and-drop music-making idea with Retake, but is a separate game project with its own presentation. It is not a Retake level or a sequel.
How to play Sprunki Mustard
Build your sound
Drag a sound icon from the palette onto an empty performer. Add sounds one at a time so you can hear what each contributes.
Change your mix
Use the game’s performer controls to change the mix. Use its reset control, or Restart above, when you want to begin again.
Characters and sound icons
Sprunkstard organizes its sound characters into Beats, Effects, Melodies, Voices and Allstar sounds. The icons below are examples from those groups, rather than a character-name chart borrowed from another Mustard game.
Beats
Try a rhythm on its own before adding other layers.
Effects
Add one effect and compare how it changes the rhythm.
Melodies
Leave room for a melodic line instead of filling every slot at once.
Voices
Listen to a vocal layer against a small backing mix.
Allstar sounds
Explore this build’s additional sound group after learning the main palette.
Tips for your first mix
Build a small yellow band
Start with one beat, then add a contrasting effect or melody. Listen to a full repeating phrase before changing the next sound.
Compare the sound groups
Try one icon from each group separately. Keep the layers you enjoy, then remove a busy part if it masks the rest of the mix.
Keep this version separate
Sprunkstard and Colorbox Mustard are different project names. Controls, character lists or combinations from another Mustard game may not apply here.
Sprunki Mustard FAQ
Is Sprunki Mustard free to play here?
Yes. You can launch this game here without paying, registering, or downloading an app.
Is this the same game as Colorbox Mustard?
This player is titled Incredibox Sprunkstard [If sprunki were in mustard]. We use Sprunki Mustard for this specific project; other games called Mustard or Colorbox Mustard may be different.
Is Mustard part of Sprunki Retake?
They are separate community-made mods in the wider Sprunki music-game ecosystem. Mustard is not a level inside Retake.
Can I play on a phone?
The player supports touch input and a landscape view. Tap inside the game to start sound. If you encounter a device-specific issue, tell us your device and browser using the contact link below.
Does Restart save my mix?
No. Restart reloads the player and clears the current session. We do not promise a recording, export, or account-save feature.
How many performers can I use at once?
This build has seven positions on the mixing stage. Add sounds to empty performers; use the game’s character controls to change an occupied position.
Why does the first launch take longer?
The player downloads the game’s images and sounds before it can start. Follow the loading progress and keep the page open. Your browser may reuse cached files on later visits. Restart clears the current mix.
Do I have to install an app or watch an ad?
No app installation or advertising break is required by this site’s player. Launch the game here and interact inside the player to start the music.
