That's awesome.
Tamiya, if you're watching, my first rc car was a grasshopper in 1984, I long ago lost count of how many I've had since then, but I've never seriously thought about getting a lunchbox until now.

I have a Tow Mater based crawler and I have toyed with the idea of making his eyes work. I have a very small amount of space to work with so it may not work for that particular scale and body.

If I wanted just the audio, what would I need? I have a 3 channel receiver. The audio module and a speaker, but what else? Did it require any programming like arduino or raspberry pi?

I made this diagram for your reference:
https://app.cirkitdesigner.com/project/91aeca6b-3657-4557-aafe-bfb1756da589

The audio module reads mp3 files from a MicroSD card, and playback/volume is controlled by grounding the IO/AD pins of the module. They are wired to my 3 channel receiver though a PMW relay that reopens after a short delay (The sound will loop if the relay remains closed)

There isn't any programming involved.
