Go to the jungle screen with the sleeping parrot. Grab the glass shard from inventory. Move the glass shard so that it shines light onto the parrot.

If you're still having trouble with the Merman game, try these tips: Let's number the buttons this way: 1 2 3 4 5 6 7 8 9 To solve the puzzle you need make the lights form a square pattern. (only lights 1, 2, 3, 4, 6, 7, 8 and 9 are lit.). Notice that the different buttons have a different effect on the lights. Pressing a corner button (1, 3, 7 or 9) flips its own light as well as all the lights around it. Pressing a edge button (2, 4, 6 or 8) flips its own light as well as the lights of the two nearby corner buttons. Pressing the center button (5) flips its own light as well as all of the edge buttons.
