How to Make a Zombie Pet in Minecraft

Well, for starters, you could dig a hole and put a bed down, or give it a slime ball as a chew toy. You could even make a texture pack and turn beef into puppy chow.

Because zombies only spawn at night. If a zombie is in light, it will burn.

You can be in any mode; however, in survival mode, you'll have to get all the materials needed.

In the original Minecraft, you cannot spawn any other mobs, the ones you can spawn are: Ghast, zombie, pig, cow, chicken, bat, skeletons, rabbits, blaze, wolf, slime, magma cube, and so on. You can download a Pikachu world and see how it is.

In Minecraft, there are no "Crewmates". Unless you download an Among Us mod, you won't have any crewmates in the game.

Zombies don't eat. They do pick up weapons, so you can throw weapons if you want to. Spawning villagers can be a way to feed it.

Not if you stay out of its melee range. Also, zombies (all types except drowned) can't use picked up bows or crossbows (instead using them as melee weapons) so you don't need to worry about ranged attacks. For Baby Zombies, either hit them with a Splash Potion of Slowness, or drink a Speed Potion to prevent them from getting too close to you. For Husks, same as the first two, depending on whether its a baby or not. Drowned are mostly like the others, except they have a chance to spawn with a trident. In that case, a shield is highly recommended (unless you're looking to try dodging the whole time).

While Minecraft Zombies don't technically eat anything, an argument could be made that they eat player and villagers (maybe baby turtles too, although they seem more interested in smashing the eggs than eating them).

Hulk is not a mob that exists in vanilla Minecraft, so you'll need to download a mod that adds Hulk to the game first. After that you could probably use a spawn egg or the /summon command to spawn him in, although it may differ from mod to mod.

You could if you want, but the article is meant to show you what to do in Survival Mode.
