Aquatic skeleton with a harpoon

An aquatic skeleton that can spawn in any ocean biome and wields a harpoon it launches at the player (similar to a trident). The harpoon is crafted with a prismarine shaft and a coral tip; the specific type of coral determines the effect inflicted upon the player upon impact: red coral causes knockback; blue coral applies an effect that makes the player sink faster; pink coral applies an effect that causes the player to rise to the surface; yellow coral applies an effect that causes the player to burn when exposed to sunlight after leaving the water; and purple coral applies an effect that causes the player to burn when exposed to moonlight after leaving the water. The harpoon's effect lasts 15 seconds; the shaft is crafted from 6 prismarine shards (requiring 2 shafts to make the harpoon), and the tip requires 9 coral blocks of the same type to create reinforced coral—with only 1 block needed for the tip itself—meaning a total of 2 prismarine shafts and 1 reinforced coral block are required to craft the harpoon. The harpoon breaks after being thrown and striking an entity or a block.
