Block of Monster

I had an idea for a "joke item" called "Block of Monster".
Basically the ingredients would be 3 rotten flesh, 3 spider eyes and 3 bones.
The block could be purely decorative, but I think it would give players something else that they can use their stacks of Rotten Flesh for outside of feeding Wolves and trading to Clerics. It would also help with the inventory clutter. Lots of players don't engage in the Potion mechanic so it would give another use for Spider Eyes and also give builders another "spooky" block for haunted houses and similar builds.
If we wanted to give it a practical purpose, I suggest making it a Compost-able material that can go into the Composter. It should also be flammable like wool.
