Sell Lemons Sewer Key Guide

The Sewer Key unlocks the Cosmic Cash Vine behind a locked gate in the sewer maze — granting 30 minutes of current income every four hours plus the Cosmic Farmer badge. Getting it requires activating four colored levers in an exact seven-step sequence. Pull wrong and the puzzle resets, so follow this guide precisely or join a fresh server to clear stuck levers.

Lever puzzle — 7 steps

StepLeverAction
1 Blue Pull ON
2 Red Pull ON
3 Green Pull ON
4 Red Unpull OFF
5 Blue Unpull OFF
6 Purple Pull ON
7 Red Pull ON — opens key door

Route tips for each lever

Blue lever: hallway near the green-text sign. Red lever: easiest to find, past the forest gate left corridor. Green lever: pathway right of the Most Cash leaderboard. After steps 3, backtrack to unpull Red then Blue. Purple lever: past green text, turn at the red floor line — several sudden turns. After step 7, a door opens on your right leading to the Sewer Key pickup.

Pro tip — respawn shortcut

Use the respawn button immediately after each lever pull to exit the maze instantly instead of walking back manually. Join a private server to follow along without other players toggling levers. If levers are stuck from a failed attempt, leave and rejoin a fresh server.
