Golden Key

The Golden Key is an item featured in the "Quest for the Potion of Power" episode of Captain N: The Game Master. It is a crucial item in obtaining the Potion of Power. Found inside the Parapa Palace, the Golden Key is initially encased in glass along with a parchment when Link, Princess Zelda, and Kevin arrive. When Link shatters the glass with his sword to obtain the key and the parchment, Horsehead appears in the room and reveals to be the guardian of the Golden Key. Kevin helps Link defeat Horsehead, allowing the heroes to read the parchment and find out that the Golden Key is used to unlock the Golden Door in the Island Palace.

Once Link, Zelda and Kevin reach the Golden Door in the Island Palace, Link uses the Golden Key on the door to open it, which reveals the chamber where the Potion of Power is located.
