<think>Target shape: pink square at (0, 6)
Distance from target shape to yellow trapezoid at (5, 0): 11
Distance from target shape to green rectangle at (5, 2): 9
Distance from target shape to brown square at (2, 5): 3
Distance from target shape to red right_triangle at (5, 6): 5
Closest shape is the brown square at (2, 5) with distance 3</think>
