Wonder Boy in Monster World/Lilypad: The Dwarf Village

Somewhere in the jungle you can find a small village called Lilypad. Once you've reached this town, talk to the villagers. They will tell you that one of the dwarf children has been captured be the monsters.

Leave the village and continue to the left, where you'll find the monsters who have kidnapped Hotta. After you have defeated the monsters, Hotta will return to the village. Talk to his sister and Hotta will join you. Hotta is very strong and is an expert in finding secret areas. Take him to the ruins, right from the village, and he will open the entrance.

Before you enter the ruins, make sure you've bought the best armor. Once inside the ruins walk to the left, don't mind the darkness for a while. At the end you'll see a button, jump on it and enter the room to the left. There you have to fight a giant bat. Use your firestorms to get rid of him easily. After you've defeated him you will receive the lamp.

Go back right to the button and go down the ladder. Go down and watch out for the big boulders. When you're at the point with the gap go to the right. Make your way to the room with the button and activate it. Now go back to the right and you'll notice that a few bricks have changed color. These gray blocks can be shattered with your sword. Walk to the middle of the room and wait until Hotta makes the entrance appear to a room with a heart container. Get it and get back to the big gap. Jump on the ladder and proceed to the left. After a while you'll enter a room with a chest. Jump on the moving platform and then jump on the bricks at the right side. You'll notice that the stones collapse when you stand on them. Now you're able to press the switch. Jump on the moving platform again and break the blocks with your sword. Now you can continue to the right. At the end of the room with the ghosts, fall into the gap.

Walk to the left first. There you'll find the shell shield in a secret room. Get back to the right. Now you'll see a room with 4 buttons. Press them in this order: 2, 3, 1, 4 and fall into the gap that has now appeared at the end of the room. Gragg & Glagg are waiting for you. Defeat them to get the Trident.
