Create a Minecraft Bedrock structure for a 10th birthday celebration. The centerpiece should be a giant birthday cake castle. Surround the castle with diamond block accents, a giant music box area, and statues of black and brown cats (specifically resembling a cat named Brownie). CRITICAL: The maximum footprint of this entire build MUST be exactly 64x64 blocks or smaller. Do not exceed 64 blocks on the X or Z axis. It must fit within a single Structure Block bounds so it exports as one single, 1-part .mcstructure file.
