Your Gumball comes already loaded with 30 cool audio tracks. But we know everyone has their little ‘special’ sound they like 🎵! So we made it possible to add custom tracks! All you have to do is load some mp3 files on the Gumball’s microSD card:

• ⚠️ Unplug your Gumball!!
• Open your Gumball by removing the cover lens.
• Slide the microSD card holder outward, then flip it vertically.
• Remove the microSD card
• From a computer, load your mp3 files on the microSD (use the provided SD card adaptor)
• Make sure the audio track names are numbers only, for example: 4.mp3, 18.mp3, etc…
• Re-insert the microSD card inside your Gumball, put the lens back on, re-plug it. Done!

Audio Considerations

• File types accepted: .mp3
• Best result with shorter tracks (~10sec or so). Audacity is a great free tool if you want to trim or edit an audio file.
• File naming convention: use numbers only. For example:
  • 1.mp3
  • 2.mp3
  • ….
  • 44.mp3
  • 45.mp3
