Finding the Temple

• 1). Log in to your Poptropica account or begin a new game. If you're on another island, return to the blimp and select "Shark Tooth Island" from the main map.
  
  
• 2). Head right until you reach the Booga bay. You pass through the ancient ruins, and avoid falling coconuts, which will knock you backward. Find the Grass Skirt stand.
  
  
• 3). Speak to the stand attendant for a grass skirt. Open your backpack to put on the skirt.
  
  
• 4). Return to the Ancient Ruins and jump over the large rock, to the left side. Click the rock to push it under the vine to the right.
  
  
• 5). Climb up the rock, then up the vine. Avoid coconuts, as they'll knock you back down. Climb to the top to find the medicine man. Select "What else can you tell me?" from the list of options, and he'll tell where the recipe for the sleeping potion is.
  
  
• 6). Jump back to earth. Head left until you find the temple entrance and go inside the mouth.
  
  
• 7). Climb all the way down, avoiding the purple bats who will try to knock you over, until you reach a panel.
  
  
• 8). Click the panel to enlarge it. You'll see a face with a row of sharp teeth. Click the second and last tooth on the top row, and the last two teeth on the bottom row. Click the nose to open the panel, and go inside.
  
  
• 9). Jump down to the bottom, avoiding obstacles on the way down. At the bottom there's a shark statue.
  
  

Collecting Ingredients

• 1). Jump up onto the shark, then onto the moving platform and head left. Jump down into a pit with spiked walls. You'll find a skeleton. Click the skeleton to get the bone from its mouth. Head right again to find the statue.
  
  
• 2). Jump back up and go left, and use the moving platform to pass the spike pit. Go left until you reach a passageway and a green vine. Jump down to find the pedestal with an urn containing a green liquid. Take it.
  
  
• 3). Climb the vine above the pedestal until you reach the surface.
  
  
• 4). Continue right until you find the carbonated coconut milk seller. Get some, and you have all three ingredients.
  
  
• 5). Return to the medicine man. Give him the three ingredients and he'll make the potion for you.
  
  

Calming the Shark

• 1). Jump down, then head right until you reach Booga Bay.
  
  
• 2). Click the cannon by the "Feed the Shark" sign, and load the potion-filled coconut. Click to aim and fire the cannon. The shark eats the potion and falls asleep.
  
  
• 3). Cross the water to the island. With the shark asleep, you will have no problem. Find Prof Hammerhead. He will ask you to lead himself and the boy to safety.
  
  
• 4). Swim back across the bay to bring the boy back to his mother. The Professor rewards you with the Shark Tooth Island medal.
