HedgeHog with cutout for LED board nighlight

I modified Lovely Hedgehog by scaling it up and making a cutout on its back to insert a high-brightness RGB LED board. I separately made a 'cartridge' that holds the RGB LED board and fits tightly into the cutout. The cutout itself is kind of a work in progress at the moment. It serves its purpose and blends into the back of the hedgehog well, but it is kind of fragile. The RGB board is also a bit of a work in progress. It currently fades through the color spectrum well.
