Updated PicturesThere should be recipes for all the mob eggs in minecraft. So you can be able to craft one and spawn in your own pig, say. The recipes I thought of work like DNA I guess. To make a ghast egg, you need a ghast tear, and then a zombie pigmen, you need a pig egg, and rotten flesh. And also. ALL mobs will act differently depending on where they are spawned. So I will give a description. Also, if it works this way, then it would also apply to both survival and creative.
Here are the pictures:
Creeper: Safe in nether and overworld.
Skeleton: Burn in daylight. Safe in nether.
Spider: Safe. Hostile at night and friendly during day. Always hostile in the nether.
Zombie: Burn in daylight. Safe in nether.
Slime: Safe. Turn into magma cubes when they are spawned in the nether.
Ghast: Safe in the nether. Die instantly in daylight. Safe at night. Can die in water.
Zombie Pigman: Safe in the nether. Burn in daylight. Safe at night.
Cave Spider: Safe.
Silverfish: Die in the nether. Safe in the over world.
Blaze: Safe in the nether. Safe in both daylight and at night. Die instantly when raining, or when they touch water.
Magma Cube: Safe in the nether. Safe in both daylight and at night. Die instantly when raining, or when they touch water.
Squid: Safe in the over world. Die in the nether.
