Keep the goal in view
The official objective is a short chain: explore the Potato Mountain, peel potatoes to locate one hidden key, use it to unlock the Vault, then escape. Start by orienting yourself and learning the interaction prompts shown in your current session.
Use in the current game
Treat peeling and exploration as the means to search for the key. When the key is found, return to the Vault and try the unlock interaction described by the game. The official page does not publish a fixed spawn, map, or guaranteed number of peels, so avoid relying on unverified coordinates or counts.
