Vertical video. Empty location, no characters. 3D Pixar animation style, macro perspective. POV from INSIDE a completely sealed, dark, wet, smooth cylindrical tunnel. It is a dead end, curving downwards into absolute blackness. The walls are dark, slimy, and barely visible, fading into pitch black depth. NO intersecting tunnels, NO grates, NO external light shafts. Eerie, claustrophobic atmosphere, extreme close-up on the wet smooth texture of the walls. /imagine prompt: Vertical video.
