Soft-Shelled Turtle Opens Sliding Window on His Own and Gets Inside

This six-year-old soft-shelled turtle, San-chan, opened the sliding window on his own with one of his limbs and got inside the house. The owner occasionally lets the turtle sunbathe on the balcony but in the past year and a half, he started opening the window and returning to its tank inside the room when left on the balcony. The owner never taught the turtle how to open the window, he learned by himself.
