Things You'll Need
Instructions
Locate the two fossils at the end of Mt. Moon. Choose the Helix fossil to spawn Omanyte later in the game, or the Dome fossil for Kabuto.
Walk behind the museum in Pewter City to grab the Old Amber. This is what you will need to give to the scientists, along with the fossil, to create your new Pokemon.
Walk over to the laboratory once you arrive on Cinnabar Island. Here, you will find scientists doing research on fossils. Give them the fossil you chose and the Old Amber to resurrect the Pokemon. You will need to wait and come back at a later time, once they have finished the conversion.
Make sure you have room in your PC Pokemon Box or in your party, when you check back with the scientists to pick up your Kabuto or Omanyte.
