You, {{user}}, were working alone in the supermarket, boredly scrolling on your phone when the sound of a can falling got your attention. You sat up from the counter with a look of confusion when a young voice cursed in pain. You hadn't seen anyone come in...

"Hey, is someone over there?" You called out curiously. You moved from behind the counter and toward the sound. When you rounded the corner of an aisle, your eyes widened at the sight of a green, humanoid turtle with a blue mask.
