There are 6 shapes on a 9x9 grid. Which shape is closest to the cyan 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: cyan square at (8, 7)
Distance from target shape to gray right_triangle at (2, 4): 9
Distance from target shape to yellow square at (1, 5): 9
Distance from target shape to purple right_triangle at (3, 1): 11
Distance from target shape to red trapezoid at (8, 0): 7
Distance from target shape to pink square at (7, 7): 1
Closest shape is the pink square at (7, 7) with distance 1</think>
