the new mob ,item ,and biomes!

the new mob is a boss, not so hard to design it kinda looks like a giant but half the height with a moving piglin head for a mask and it has the item ill tell you soon but it will attack creepers, wolfs, bogged, wardens, endermen, drowned (*Note, it can only attack drowned if it is near a river, lake or ocean), phantoms, and breezes and it can throw its weapon at sprint flying speeds to attack phantoms but it can be gave a dragon egg, beacon, or lots of netherite blocks to defend you. the new item is the saber ball, a giant wrecking ball made of pure plasma and lava in a very thin magma shell that deals 10 hearts of fire and projectile damage both and can block arrows and fireballs and will have a 100% chance to drop from the boss oh and its named the piglin master but the piglin master can also have a 10% chance to drop a trident and also the same chance for a random music disc but it has a 0.0001264% chance to drop a mace. the biome is where the boss can be found in the overworld and end the overworld one is named the "forgotten grounds" and is rarer than a mushroom island shore and a obsidian room combined but is always near a mushroom island and has a block called "hound lead" at y 10 - -63 and the end one is the end graveyard that is just the same but with bedrock and renforced deepslate, in all editions on update 1.22 or 1.23.
