Realistic gamemode

A gamemode without the bad mobs. No zombies, skeletons. The bones should be buried in the ground så when you dig you can find the bones. We as adults and parents to playing children loves the Minecraftconcept bit not these parts. We like to play for relaxation, but these mobs is stressful. So a realistic survivalmode would be awsome. So you have to find all material as usual but removing the unnatural elements and tou have to eat. But animals of course should be in the mode (living ones). Evil mobs that can be kept might be pillagers, they are almost realistic. So crossbow and bows you simply have to build.
