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
| Step | Lever | Action |
|---|---|---|
| 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.
