Project Finding "Nory" (Dory + Nemo) build/custom

Mr Ripley, if you can find it definitely a neon orange sandstone type spray for the tracks, go on do it, do it, do it!!!

You could get some of those small metalic type coloured beads used for making necklaces to go in the bottom of the clear coaches, they should be small enough to look good, but big enough not to leak out of any holes

What if we tried a sandy texture with neon blue, green, and orange spots on top? I know the sand one exists. A few years ago Mom bought a can of spray paint for my older brother's school project that's meant to look like sand with some speckles of rock and grit in it, and it really does look just like that.
