New Mob idea

So at school I was bored with the square papers then I decided too create a mob ( didn't create it but I did the design ) it's a narval , I realized that there's not alot of sea mobs so I drew the narval I think it would be a good addition too the game if possible. I didn't think of what it would do yet , give me a few minutes il be right back. Yes so if you kill them you can get their long horn and with it you can make reinforced iron ? If you put it in the middle and iron around it in a crafting table you can make reinforced iron beacause we need more reinforced stuff with it you can make a sword,pickaxe,axe,hoe and armor. A cool special thing additional if you take a mace put it in the middle of the crafting table and put reinforced iron around it the make you make a little more damage, alot more of durability but the wind burned effect would be less stronger , you can make reinforced iron blocks. Beacause sulfur cubes came not a long ago if you put à reinforced iron block in the sulfur cube it's super heavy but falls super fast that's all my idea right now and have a good day 😊.
