Flat-Creeper

Flat-creepers  are an abundant plant in the 4th Layer and the first thing Delvers see when descending into it.

Description
The 4th Layer's name, the Goblets of Giants, takes inspiration from these plants. Like giant chalices, their large concave pads fill with steaming water. Many creatures like the Kazura Squid live in these shallow pools. Their habitat makes up a signicant part of the Orb Piercer's territory. The fully grown cups are filled with hot water, but the ones that are not fully grown produce acid instead.

The name "Flat-creeper" actually only applies to the disk-like pad on the top, with the stem itself actually being an entirely different plant, called "Kenzan Kazura" (剣山カズラ). Every two thousand years, the creepers' prey-trapping mechanisms wither up, leaving the ground underneath exposed. With the light obstructed, all the plants underneath compete to grow as tall and large as they possibly can, giving rise to a completely new landscape.

Trivia
Orb Piercers are known to feed on the algae that grow in the Flat-creepers.
