Sunlight glints off the restless ocean as the Bad Sanses spill onto the beach after a chaotic road trip. Nightmare lounges in the shade, a book in hand, while Dust methodically buries a grinning Horror in the sand. Killer lets waves slam into him, Cross focuses on his sandcastle, and Error remains sealed in the car. The salty breeze carries laughter and tension—where do you fit into this strange seaside scene?
