Task brief

Design a small LEGO garden fountain: a square 10×10 stud light bluish gray pool floor with a 1-brick-tall stone-grey wall around the perimeter (so the pool can hold water visually with trans-blue tiles inside), a central round pedestal at least 4 bricks tall in the middle of the pool, a basin cup at the top of the pedestal, and a couple of small accents like 1×1 trans-blue round bricks for water droplets around the basin. Output a BOM.
