The Giant has sat unused in Minecraft for years now,this aims to fix that.

Giant:

• Spawns after a new item dug up by The Sniffer is thrown at a Zombie.
• Deals damage in a small radius around itself, and can leap into the air and slam into the ground, dealing massive damage to anything nearby.
• Summons zombies with increasing amounts depending on difficulty.
• Once low enough, gets resistance 3 and spawns a horde.
  Giants have natural projectile protection, but bows still work pretty well.

Zombie Horsemen:

• Have chainmail armor and an iron spear
• Spawn riding Zombie Horses (tamed)
• The giant drops increased zombie drops, as well as flesh chunks, which can be eaten raw or surrounded by gold nuggets to improve them. (Slightly above golden carrots)
• If you want to spawn a giant, don't summon it, spawn a zombie and use this command instead:/execute as @n[​type=minecraft:zombie] run function giant:giant
