Super Mario Sunshine/Walkthrough

Delphino Airstrip
Watch a scene, and after that go to the corner of the airstrip without touching the goop and get FLUDD and watch yet another scene. Once the scene is over, go over to the goop and spray the center for a short time until a Goo Monster comes out. To defeat it spray its mouth three times and out comes a Shine Sprite. SHINE! Save the Pianta in the goop if you want. Now watch another scene. You will now be in Delfino Plaza.

Delphino Plaza
After the scene, go down to the Main Square. Defeat the Goo Monster like the one in the airstrip, but be careful because this one makes Goopys. Once it is defeated watch a scene(with all these scenes, you should bring popcorn). Now chase Shadow Mario while spraying him(the music will get louder or softer depending on how close you are). After you defeat him talk to Peach and follow her orders. Shadow Mario will escape into the grafiti. spray it until light comes out of it. Now, jump in. Now you are in Bianco Hills
