Creeper spores

If a creeper explodes creeper spores fly in every direction. On their own they are useless and will de spawn after some time. They can be picked up with a silk touch tool and placed on fertilized land. It will grow in a similar way crops grow only a bit slower. Once it finishes growing it will turn to a creeper unless there’s a cat in the distance of less than 4 chunks away or any other animal in the same chunk. If it grows fully and doesn’t spawn a creeper you can harvest it and get explosive flesh which can be used as an ingredient for new potions - the potion of blast resistance that reduces the damage the player receives from explosions (a weak potion reduces the damage and a strong one eliminates any damage). If you add a TNT to this potion you get the potion of explosion which doesn’t shield you from explosions but when the potion wears out an explosion will happen around you similar to the explosion of a creeper. If you add a netherite ingot you will get the potion of many explosions which means that many explosions will happen around you. To avoid lag, their won’t be more than one explosion happening at a time - the second will start only after the first ends. For farming this new resource you will be able to use any animal in the game but if you want to use this to defend your base the only practical way is to tame a cat which will give cats another use.
