please see all 23 actual photos showing exactly what buyer will receive in working order to be honest i am not sure what the different color foam pieces are from pepperonis to mushrooms some of the pieces are new and some of the foam pieces i just pushed back in place i tried to point out in photos 15-17 i believe, i did notice the in the black foam and red foam each has 2 pieces missing but if the red ones are pepperonis that is correct but i am not sure so please feel free to ask any questions i will do my best to answer it does take 4 AA batteries (not included) but was tested before listing so be sure to see them all and zoom in
