Diamond and Netherite Golem

There should be a Diamond and Netherite Golem. The Diamond Golem is a tamable mob. It is built by putting diamond blocks in this shape:
                              [Air] [Diamond Block] [Air]

[Carved Pumpkin] [Air] [Diamond Block] [Air] [Carved Pumpkin]

[Carved Pumpkin] [Air] [Diamond Block] [Air] [Carved Pumpkin]

                              [Air] [Diamond Block] [Air]

Turning into Netherite:
The Netherite Golem is spawned by placing Red Debris in water (which is obtained by combining 9 netherite pickaxes in a crafting table), eventually turning into a Nethereater (which is a block), which can be breaded with the Diamond Golem to produce an egg that goes in the water. The egg will hatch into a Netherite Kid, which can only survive in water, which grows up into a Netherite Golem, which can survive on land. Their favorite food is diamonds.
