The initial transition from a fantastical animated world to a real-world block-building scene.

The ad opens with a vibrant, blocky, animated landscape that transitions to a real-world scene of a man building with blocks, accompanied by a white llama. It then shows blocky characters and structures, including a pink house and sheep. Jack Black appears, pointing to a pink house. The title card 'THE BLOCK PARTY' appears, followed by a scene with pig-like monsters and the text 'This pig is mine.' The title card 'COMES HOME' appears. The final scenes show characters interacting in a blocky environment, with action and movement, before transitioning to the 'A MINECRAFT MOVIE' title card and HBO Max branding.
