There are 6 shapes on a 5x5 grid. Which shape is closest to the blue 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: blue square at (1, 2)
Distance from target shape to yellow rectangle at (2, 3): 2
Distance from target shape to red right_triangle at (2, 0): 3
Distance from target shape to orange square at (1, 4): 2
Distance from target shape to gray right_triangle at (4, 2): 3
Distance from target shape to green square at (1, 0): 2
Closest shape is the yellow rectangle at (2, 3) with distance 2</think>
