Change and add new blocks

Rascal - Spawns in mineshafts with the same functionality as before, but trade a lot more of loot (it trades with you when you find by the 3rd time), being any item you can found in mineshafts at the biome it spawned (ores, things that generate in chests and the materials used to build it), a enchanted iron pikaxe (with looting II and efficiency IV), clock (in sulfur caves), bread and beef (spawns rarely)
Glare - Spawns in lush caves and swamps with the functionality that had before
Cave bettle - Like a cave spider, but neutral during the day and hostile during the night, also gives more damage (spawns rarely)
Sulfur cubes - Have 3 new arquetypes (light, redstone, sticky and slime) the redstone (only redstone block) activates redstone, the sticky is just a change to add honey blocks and stick to walls and roofs, the slime is the bounciest arquetype
Copper Golem - Also prees copper buttons
If any of those be added would be nice, so plese at least add one of them
