Wonder Boy in Monster World/The beginning

Leave your house after you have read the story. To do this, stand in front of the door and then press down (press down to leave a house or shop and up to enter one). Walk to the right and enter the house in the tree trunk. Talk to the fortune teller by pressing up (press up to talk to a person or to buy items). After the fortune teller has informed you about your dangerous journey you will receive an elixir and 3 pieces of Fire Storm magic. Leave the house and jump on the moving platform. Jump on the tree trunk to get some extra coins, then continue to the right.

Buy the Leather Boots in the shop here, you can collect the money you need by killing the snakes. When you are ready, continue to the right and past the soldiers. Now you will enter the Monster World Sea. Cross this sea to reach Alsedo. At the end you will see a jumping jellyfish. For those with poor reflexes this is harder than it looks. There are four jellyfish, but if you are wearing the boots you probably won't need the final one. Anyway, get across and onto the opposite cliff.
