Giant

Giants are over-sized mobs that were added in the last version of Survival Test. It uses a six times enlarged Zombie model and the sounds of the Player. They are twelve blocks tall. Like Zombies, Giants' only method of attack is to charge into the player. Since Survival Test, Giants have not been used, and they do not spawn naturally. As of 13w36a, you can use /summon to spawn Giants. Giants have not been removed and are unused. Unlike normal zombies, Giants do not burn in the daylight and can be dangerous all the time although there is a glitch where they do not attack after a while.

Behavior
Giants when spawned in the game are hostile. They can see a player from up to 16 blocks away. They use the same skin as zombies yet share almost no similar behaviors. The only exception would be their style of attack ; Giants attack by simply ramming the player repeatedly, in the same manner as zombies. Oddly, despite its massive size, Giants can not break blocks. They also only jump one block high, which, in comparison to their massive size, makes them appear to lack the ability to jump. Giants have a difficult time attacking players unless the player pushes themselves into their legs.

Unlike Zombies, Giants are not set on fire by sunlight (although they are not immune to fire damage), and also do not have any idling sounds. They make the same sound as the player when hit, and drop 5 XP Orbs upon death.

Issues
Note: keep in mind this is not a supported mob.

Trivia

 * A giant can inflict huge amounts of damage. However, they do have the tendency to get stuck in thick biomes with many trees. This is the perfect opportunity for the player to attack it, since it can no longer move.
 * Giants can be considered the least detailed mob. One pixel is 3/8th the size of a block.
 * Giants used to have the most health out of all the mobs, but since Minecraft 1.2.3 they are on par in health with the Iron Golem and have less health than the Ender Dragon and the Wither.
 * Iron Golems and Snow Golems will attack a giant, as if it was a hostile mob.
 * Prior to 1.0.0, arrows fired at Giants would stick in them, but the size was not proportioned properly, giving the stuck arrows a giant sized appearance.
 * Using an inventory editor or cheat codes, the player may give themselves a mob egg for the giant. However, the egg is not usable and will not spawn a giant when right clicked. To get the egg without an inventory editor type a command such as  . 53 is the damage value (using an entity id as the damage value gives you a spawn egg with that entity, but most of the non-standard ones don't work).
 * The only way to spawn a giant is to use the Summon command, typing in.
 * Despite using the same skin as Zombies, Giants are not considered an undead mob, so they are damaged by Potions of Harming and healed by Potions of Healing.
 * Giants are one of the only mobs in the game that don't spawn naturally, with a spawn egg or by a pattern of blocks, along with skeleton horses and zombie horses and Green Robe Villagers that still exist in the game
 * In the code, giants need to have a light level both less than 8 and greater than 11 to spawn, but since that can't happen, they don't spawn from mobspawners. However, this spawn condition can be bypassed with a custom spawner, if it attempts to spawn an entity with valid spawn conditions riding a giant.
 * The reason Giants do not act like zombies is likely because they are intended to be a living mob, but they never bothered to add a different texture.
 * Giants are implemented into the Xbox 360 Edition, although they require external modifications for their egg to be placed in the player's inventory.
 * Iron Golems can fling the Giant, in spite of its huge size.
 * If you spawn a Giant using /summon, the Giant will not make sounds. This is because the Giant's sound files were removed before 1.7.2.
 * Even though the Giant won't take damage if you hit it above the legs area while it's standing, it will still take damage if you shoot it both in the legs and above.
 * Giants will drop Experience Orbs, but not other drops.
 * Like other mobs, Giants are reluctant to cross rails.
