Gather materials: 4 copper blocks and 1 carved pumpkin
Place 1 carved pumpkin on top of where you want the golem
Place the 4 copper blocks in a square around the pumpkin (leave the center empty)
Ensure the structure is complete and aligned so the pumpkin sits directly above the center
Activate the golem by ensuring it forms after placement (it spawns as an entity)
If it does not spawn, break and re-place the copper blocks and pumpkin, maintaining the exact 4-block square layout
