Add explosive pizza and troll fish
Explosive pizza is a block that kinda has the same shape as cake and when you right click it it makes an explosion (and you also restore some hunger)
Explosive pizza is crafted with 3 TNT and 1 pizza
The pizza is crafted with one bread, one cheese and one piece of meat (can be chicken, fish, beef, even mutton!)
Cheese is a item crafted when you put milk in a cauldron for a few minecraft days and then pick it up with a shovel. If the milk sits for too long, it expires and becomes expired milk (it poisons you when drinked)
Troll fish is a fish that when you come too close, something bad happens like tnt falls on you, you lose all of your items, a charged creeper with speed 5 comes running at you. If you kill it, it will give you the mysterious potion.
If you drink the potion, either you will die (and all items get deleted) or a 50% chance of whenever you sleep you teleport to the diamond dimension and you can bring tools with you but if try to break a block you wake up with poison, mining fatigue, nausea and other bad effects
Also a small bonus idea: When you raid villager chests, all of the villagers in the village summon an iron golem each that all have speed 5 and strength 5 and all of the iron golems attack you and they have more range so that you cant pillar up to escape them. They wont stop chasing you until you die and if you punch a villager, same thing but each villager summons 5 iron golems.
