'minecraft:zombie_pigman', 'minecraft:wither_skull', 'minecraft:husk', 'minecraft:ender_dragon',
'minecraft:cave_spider', 'minecraft:guardian', 'minecraft:silverfish', 'minecraft:stray',
'minecraft:vindicator', 'minecraft:endermite', 'minecraft:magma_cube', 'minecraft:spider',
'minecraft:vex', 'minecraft:zombie', 'minecraft:creeper', 'minecraft:wither', 'minecraft:zombie_villager',
'minecraft:evoker']
Its to big for 256 chars.
