Conkers

Dark oak trees could drop conkers since theyre similar to horse chesnut trees. It would make the woods feel a lot more enchanted if you can feel like a fairy running around wearing green spiky conker armour. A new differently shaped armour would be so cool too if it had spikes.

Maybe it could have something to do with getting a thorns enchantment too. 

I think conker trees and conkers are super cool. :)

(i saw someone had this idea too im glad im not the only one thinking about it)
