Pinecone

A Pinecone is an item that is obtained by mining Spruce Leaves. When obtained, the player can place this as a block, or they can put it in anywhere in a crafting grid to split it into 9 Pine Nuts. Pine Nuts can be eaten, or the player can fill the 3x3 crafting grid with them to make a Pinecone. The Pine Nut has a Golden and Enchanted Golden variant. The Golden Pine Nut recipe is just making the Block of Gold but replace the center with a Pine Nut. The Golden Pine Nut gives 4 absorption hearts, as well as Regeneration II. The Enchanted Golden Pine Nut gives you 14 absorption hearts, as well as Regeneration II, Resistance, and Fire Resistance. The crafting recipe for the Enchanted Golden Pine Nut is filling the crafting grid with Blocks of Gold but replace the center with a Pine Nut.
The item in the inventory slot (and when placed down) is a 3D pixelated pinecone. The Pine Nut item in the inventory slot is just one of the pine nuts from the pinecone. The Golden and Enchanted Golden variants of the Pine Nut are just a recolored version. How you can tell the difference between a Golden and Enchanted Golden Pine Nut is that one looks enchanted.
