The scheme of summoning giant zombies in the game.

When the player defeats the ender dragon and returns to the main world. There is a certain chance of encountering a "ragged" wandering Trader in some places. You can exchange bread and tether for the "Undead Adventurer Map". You need to collect some carrion first, and then follow the map's guidance to come to the "Giant Zombie Skeleton Ruins". Use a certain amount of rotten flesh on the skeleton to summon giant zombies.
Giant zombies are very tall. This may allow players to use elytra while fighting giants.
