Minecraft boss: Toxin

The Minecraft boss that i've thought about is an overworld boss. It is called the Toxin boss. it has a snake-like appearance and can change its colour to the surrounding blocks. it shoots poison projectiles from its mouth (gives you the poison effect for 3 seconds). sometimes it tries to sink its razor sharp teeth into you that deals 1-2 hearts of damage. It has 100-120 hp depending on its size. The new item is a Scale, it only drops from the toxin boss. it is a mobile lighting source and can also fully repair any weapon or armor 1 time in a crafting table.
