Neverland's Keyhole is near the three o'clock point on Big Ben's clock face, and appears when the hands point at twelve o'clock. You first stop in the Brig of Captain Hook's ship, where you meet with Peter Pan. Eventually, you'll enter the ship's hold. Activating the Yellow Trinity on the left opens a small Secret Room, while the right door leads to a hole into the ship's Freezer. Traveling through the Freezer takes you to the Galley. Climbing through the grate in the corner takes you to the Cabin and a Green Trinity that lowers the ladder and allows you to access the Captain's Cabin.
