There are 4 shapes on a 9x9 grid. Which shape is closest to the pink square in terms of Manhattan distance? The final answer is the grid position of the closest shape like (row_index, column_index).
<think>Target shape: pink square at (6, 2)
Distance from target shape to green right_triangle at (1, 5): 8
Distance from target shape to blue square at (8, 1): 3
Distance from target shape to orange trapezoid at (1, 0): 7
Closest shape is the blue square at (8, 1) with distance 3</think>
