Instructions
Travel between worlds on the default Gummi ship and engage enemy ships you encounter along the route. The enemy Gummi Ship you destroy sometimes drop the blueprints for that particular ship when destroyed. Once you pick up the blueprint, you permanently have the drop.
Play the game until you are able to visit Geppetto and Pinocchio in the town of Traverse. Speak to Geppetto to get a new Gummi Blueprint bearing his name.
Visit Geppetto's house 30 times in total then speak to Pinocchio to receive another Gummi blueprint.
Kill all enemies you encounter while playing the game. They are called "Heartless" and there are several different types of them. After killing 500 of them speak to Geppetto for a new blueprint. He will give you new blueprints at intervals for killing Heartless. The last of these blueprints are obtained after 5000 kills.
Enter the warp holes when traveling along the routes. These send you to random destinations but also reward you with blueprints if you destroy enemies along the way.
