Super Mario Sunshine/Sirena Beach

Episode 1: The Manta Storm

 * Objective: Defeat the Manta. It splits into two every time you kill it.

Go to where the hotel should be — it's easy to find, it's a square of blue/yellow goop. Don't step on it or you'll get electrocuted. Clear some of it out before talking to the Mayor. There are also three easy 1-ups in this level you may want to get. On the left side of the area are three crates — the middle one holds one. The other two can be found by freeing the two Noki children on the right of the area. They're currently buried in electric goop. Clean them off for a 1-up (or a blue coin if this is the first time).

Once you're done clearing out most the goop and getting 1-ups, talk to the Mayor. He's the man standing in front of the main square, where the hotel should be. He'll tell you that a manta-shaped silhouette appeared, covered the beach in electric goop, and destroyed his hotel. Then, he'll be interrupted by its return. (What a coincidence. It must be sensitive at being called "horrible".) To fight it, spray it with water. After you hit it with enough water, it'll split in two. Spray both of those in two. Each manta leaves a trail of electric goop — again, don't step on it. They can't leave any on water, though. Two useful techniques here are hovering and spin-squirting.

Once you reduce all of them to the smallest possible size (there will be 64 by the time you've finished), they'll all turn hot pink and attack you. When you shoot these, they won't split — they'll disappear into thin air. To keep them from surrounding you, you may want to find a wall. The spin-squirt is very effective here. Once they're all gone, a cutscene will show the hotel reappearing. The shine is above the fountain.

Episode 2

 * Objective: spray the pink ghosts to make stairs to the top floor appear.

Enter the portal in the boo statue's mouth and complete the following puzzle. Remember: Shadow Mario has taken FLUDD so you can't use the hover nozzle. If you use the ground-pound/box-breaker move on the last section of square watermelons you get a 1-up mushroom.
