07 Chapter seven · Pipes, gears, and greenhouse work
Overgrown
A three-part greenhouse chapter combines gas pipes, mechanical gears, and plant preparation. It is long enough that clear handoffs matter as much as each individual puzzle.
FULL Chapter walkthrough
Complete puzzle guide
Overgrown is one long chapter made of three connected stages. Complete the gas network, survive the flooding water tank, and then cultivate the ingredients for the plant poison.
Part 1 — Pressure pipes
Mix red, blue, and yellow gas into purple, orange, and green. Route each mixture into its matching tank across both rooms without any open branch or hidden leak.
Part 2 — Gears and water tank
One explorer starts the water at the bottom of the tank while the other builds temporary gear trains. Restore each rotating platform and climb out before the tank fills.
Part 3 — Cultivation and mixture
Grow the numbered plants, prepare the red, blue, and green potions, combine them into black poison, and send the loaded sprayer to the explorer facing the giant plant.
