Common isopod, rolly polly, a pull big if you will. Constantly under decaying matter or dark damp areas like rocks and such. I have noticed variations in the sides of these where some will have much more prominent armor protrusions while other specimen will be smooth
While I could be completely wrong I think these berries that grow on it are edible, I also have felt the thorns and they most definitely hurt, would recommend wearing jeans around them.
Radish. Another root vegetable that can start growing in the fridge and does very well in the surrounding soil of the area, are very susceptible to insects though.
