harpoons!!!!!

Harpoons should be here. I think that it should be crafted from a spear with a string so it can be thrown and pull the mob when hit. I think the damage it should take depends on the type of spear and velocity when thrown, and has a 30-50 block range if it is ranged, and will do melee if not thrown. When the durability is exhausted, it will become a spear.
The enchantments I'm thinking of are piercing, sharpness, yanking, mending, unbreaking, lunge, bane of arthropods, smite, looting, fire aspect, and curse.
Yanking lets the harpoon come back faster and pull the mob toward the player, further, like 3 or 4 blocks per level.
