The Blob Below

Mildew Manor advertised itself as "vintage charm." In practice, it was humidity with beds. The walls sweated, the windows stuck, and the bathroom ceiling bloomed with a dark patch that looked like a storm cloud. Talia had read a blog about the Spore Settler incident in Book #13, but New Orleans was hot, and she wanted a shower more than she wanted to be careful.

The bathroom was a row of stalls and a chorus of dripping. The shower she chose had a door that didn't latch and tiles that felt slick even when dry. She turned the knob. The water came out warm. She didn't notice the drain because it was already dark with growth, a damp mouth disguised as a grate.

She hummed as she washed her hair, the steam thickening the air. She was texting Dex about the jazz set they planned to see later. The messages kept failing. The Wi-Fi was weak in the bathroom. She leaned back into the water, eyes closed, and felt the floor shift. The drain pulsed once, like a heartbeat.

Talia opened her eyes to see the mold creeping, a dark sheen that had not been there a moment before. It crawled in thin tendrils along the grout, tracing a path toward her feet. She stepped back, soap slick on her skin, and the tendrils recoiled, then reached again. The shower door groaned, as if pushed by a hand. The room smelled of wet earth.

She laughed because it was easier than panic. "Nope," she said, and grabbed the handle. The door wouldn't move. The mold pooled beneath it, thick as tar. She yanked again, and the door shuddered but stayed shut. The steam had turned the stall into a foggy box. The tendrils lapped at her ankles, cold and slimy, and she felt the water level rising around her feet.

Outside, Dex was half asleep in the common room. Ari was arguing with Jules about the internet, about the blocked drains, about the reviews. Jules said he would fix it next week. Ari said someone could get sick. He didn't say someone could disappear into a bathroom floor.

Talia tried to climb the wall. Her hands slipped. The mold thickened, rising like a wave. She screamed, a sound that died in the steam. She kicked the door and felt it flex. For a second, she believed it would give. Then the mold surged, covering her feet, her knees, her waist. It moved with purpose, a slow and hungry intelligence.

Her mouth filled with soap as she tried to call for help. The mold pressed against her chest, heavy, cold. It smelled like the inside of a forgotten suitcase. She thought of the hostel reviews that had said, "Bring sandals." She thought of the band she wanted to see. She thought of the feeling of sunlight on her shoulders. The mold didn't care.

When Dex knocked on the door, it was quiet. The water was off. The stall was empty, except for the drain, now clean and silver, as if it had never known growth. The mold had swallowed itself back into the floor, leaving no trace but a faint, sweet smell. Dex assumed Talia had gone back to her bunk. He went to sleep.

In the morning, a note appeared on the bathroom mirror in foggy letters: "The pipes are fed." Ari took a photo. @HostelReaper replied with a single spore emoji and a location tag. Jules ordered a new drain cover. It arrived too late.
