Daddy Yeti

A Daddy Yeti known as (Iron Golem) is a large, strong, neutral utility mob that defends players and villagers.

Villages
In Java Edition, villagers can summon iron golems, either when they are gossiping or panicking. When a villager tries to summon a golem, up to 10 attempts are made to spawn a golem within a 16×13×16 box centered on the villager (villager block position +7/-8 blocks along x/z axes and +6/-6 blocks along y axis). A random y column is picked and then the topmost block in that column is selected that is air, water, or lava, and has a "solid-blocking" block underneath, or block at y=+6 if none such is available in that column. The target location is then checked whether the block underneath has a solid top surface (which is not the same as "solid-blocking"). The target block and 2 blocks above must not be a full block, nor be redstone-powered, nor be rails, and the two blocks above must not be water. This means the iron golem can spawn inside 1-deep water or inside blocks like slabs, fences, and carpets (if other checks pass). Adjacent blocks are irrelevant, so golems can spawn partially inside adjacent solid blocks. However, the spawning iron golem still must not collide with any existing entities.

In Bedrock Edition, an iron golem can spawn naturally when a village first generates in the world. Iron golems also spawn in villages having at least 20 beds and 10 villagers, in a 16×6×16 volume around the village center defined by a bed, a bell, or another meeting point. For a village to spawn iron golems, 75% of the villagers in the village must have worked in the past day, 100% of the villagers must be linked to a bed, and a player must be within 80 blocks of the village horizontally and within 44 blocks vertically. The chance of attempting a spawn is 1⁄700 per game tick, which averages to one spawn attempt every 35 seconds. Iron golems can spawn provided the 2×4×2 space above the spawn point (that is, horizontally centered on the NW corner of the block it spawns on) contains only non-solid blocks, and the block it spawns on is solid. If the village's original iron golem is killed, a new one cannot spawn unless all of these conditions are met; therefore, small villages do not regenerate an iron golem unless the village is expanded.

Creation
Iron golems are created by placing four iron blocks in a T shape (as shown in the image), and then placing a carved pumpkin, jack o'lantern or pumpkin‌[BE only] on top of the center upper block. The pumpkin may be placed by the player, a dispenser or an enderman, but it must be placed last. It needs space around it to be able to spawn and cannot spawn in a confined area. Alternatively, the blocks can be placed in any order with an uncarved pumpkin; the player can shear the pumpkin to spawn the golem. When successfully transformed, it is naturally passive toward all players under all circumstances. It can, however, attack the player’s tamed wolves, if punched accidentally, but it never directly attacks the player.

The block arrangement can be placed upright, lying down, or upside-down. The four empty spaces in the diagram (above and below each of the arms) must be air blocks. Any non-air block (including blocks such as snow layers, grass, and water) present in any of the empty spaces prevent the golem from spawning.

Like other constructed mobs, iron golems always spawn facing south. Their large size may cause them to take suffocation damage from nearby solid blocks at the level of their head.
