Instructions
Go to the bedroom on the left side of the top floor of the Haunted House. Walk to the fireplace to the left of the bed. You will see two clocks on the mantle. Click the clocks to zoom in on the clock faces.
Position your cursor on the face of one of the clocks. This will speed up the hands on the clock. Move the cursor from one clock face to the other until the time on both clocks match.
Move your cursor away and wait for midnight to strike twice in the Haunted House. Two skulls pop simultaneously out of the top of the clocks on springs and the lantern appears inside the fireplace.
