description: 'Identical scene to Category A: three blocks (red, green, blue) on the
  black mat, a magenta cross on the white mat. The instruction states the bottom-to-top
  order explicitly.'
instruction_templates:
  all_episodes: Stack the blocks from the black mat to the white mat at the cross
    position, with order from bottom to top of {c1}, {c2}, {c3} blocks.

    order: blue-green-red
    instruction: Stack the blocks from the black mat to the white mat at the cross
      position, with order from bottom to top of blue, green, red blocks.
  3:
