Well this idea came from a dream and thought it would be cool cause we have 9 levels and in the dream I could add various insect parts on my weapons it didn't increase the attack damage to it but added there abilities like on it I added 3 spider parts to increase the attack speed 2 bee parts for critical hit chance 2 mosquito beaks for life steal 2 rolly polly shells for durability. These could even apply to armor like spider parts making you run faster.
Another thing is adding a rat not as a hostile creature but just appear once every few days and it drop its fur to make a luxury bed just for more decorations
