Episode 1: The Manta Storm
- Objective: Defeat the Manta. It splits into parts every time you kill it.
This is the Island's most luxurious hotel, but the guests are a bit irate at the moment because they have reservations but no hotel. There is a new kind of goop covering the ground though, and it's more dangerous than what you've seen up to now because it gives you a painful electric shock if you touch it.
Clean up some of the goop; there are two Nokis buried in it that will be grateful for a rescue. You can also get a 1-Up by breaking the middle box of three on the left side of the beach. Speak to the hotel manager who is right next to where the hotel should be on a large square surrounded by moat. 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.
Episode 2: The Hotel Lobby's Secret
- Objective: spray the pink ghosts to make stairs to the top floor appear.
The hotel is back but it's still not open to guests because there are ghosts all over. Talk to the manager again to be shown inside and you'll see what the problem is. There are Boos wandering around and, according to one of the hotel staff, they came out of the mouth of a statue on the top floor.
Getting there is tricky because the stairs all have emergency shutters in place. There are pink Boos floating around the middle of the lobby and if you spray them they turn into pink blocks you can stand on. So you need spray to get a block, jump up to it and spray to get a block a bit higher. Keep doing this to make your way up to the top floor. Now just hover into the statue's mouth to enter a secret level.
From the starting platform hop to the row of brick blocks on the left. Stus start coming toward you but these should be no problem. There are more bricks above you as you get near the end of the row, and you can break these from below by jumping. (Mario's head has always been very hard.) The first of these blocks has a 1-Up inside.
Do a wall-kick or triple jump to get up to the next row of blocks. There are gaps which you must get across, but there are flying Stus you can use as stepping stones. These fly left and right so you have to time your jumps. One of the blocks is made of sand which dissolves when you stand on it, so it takes a bit of extra planning to jump from it to the Stu.
You land on a ledge with brick blocks above it. Jump to break on of them at the lowest layer, then use wall kicks to get the ones above it until you can wall kick up to the top. Next follow the trail of sand blocks; if you've already done the Dune Bud Sand Castle Secret in Gelato Beach then you should be used to this, but the path here is a bit more complicated. There is a side path going down to the right but avoid it.
Now you're on a rectangle of blocks of various kinds. There are watermelon blocks at the far end and if you smash your way down to the bottom of these a 1-Up appears.
At the bottom of the far end is a gear shaped block and the next step is to jump onto it. It starts to move and turn when you do; you just need to stay on top until it takes you to your destination. The gear teeth make this rather tricky though, so make sure you don't try to go over them faster than you need to.
There is a pile of sand blocks to jump to at the then of the gear block ride. Get over to the other side being careful not to slip as you're coming down the far side. There you are met by one last Stu who is guarding the Shine.
Episode 3: Mysterious Hotel Delfino
- Objective: Discover the mystery of the hotel.
Well the hotel is finally open for business, the Doot-Doot Sisters are dancing to Ukulele music on the beach, and there are only a few Boos around to disturb the guests. Talk to the hotel manager to be invited inside and start exploring.
You'll be able to see the Shine in the pool on the third floor, but the pool monitor won't let you in with street clothes, so you need to get past him somehow. This is pretty complicated though and you will need to explore most of the hotel before you'll be able to do it.
First, you're going to need Yoshi. There's an egg right next to the hotel desk but Yoshi wants a pineapple to hatch. There is a fruit stand in the lobby but, of course, they have everything except pineapple. It seems someone is hoarding them, so you need to explore the rooms to find where the pineapples are hidden.
All the room doors are locked except for one on the third floor. Just make a note of that fact for now. There's guest in the lobby who gives you a clue what to next; he points out that there's some water damage in the Men's room. (The woman in the Women's room will chew you out if you talk to her.)
Find the stall where the water damage is and jump to find yourself in the tub in the room upstairs. There's actually a second way into this room which you can discover by jumping on the bed. It's through a trapdoor in the pool lobby. Talk to the woman whose room you've invaded and she mentions that a painting is giving off a weird vibe. Spray the painting and the picture changes to a Boo, then jump through into the next room.
There are two Nokis in here and they've got a couple of Boos in with them. Get rid of the Boos so maybe the couple will calm down a bit, then spray the panels in the doorway which connects to the next room. When all four panels are turned you see the outline of a Boo and the doorway opens.
There's a Pianta woman in here and she's got pink Boos with her. Spray to turn them into blocks as in the previous episode and go through the hole in the ceiling.
Now you're in a small room with a lone Noki; Spray the shelf to open a way to the next room. There is a Pianta in here but he doesn't seem to be a guest because the furniture is all piled up against the walls. From talking to him it seems that he's our pineapple hoarder, but he's misplaced them. There are posters here you can spray your way through but we don't need to right now. Instead, look for the patch of floor that a different color than the rest. It's a trap door that takes you down to the floor below.
There are crates in here with the missing pineapples, so pick one up and go back to the lobby so you can wake up Yoshi.
The first thing you need remember about Yoshi here is that you can't open doors while riding him. So if you go into a room with a closed door with him he'll get trapped inside and you'll have to go through the entire previous route to get him back.
Take Yoshi to the third floor and go into room with the open door. There is a Noki couple in there but they won't mind if you bounce on the bed to get into the attic.
The attic is a maze and there are several places where you can break through into the third floor again. Some of these have already been explored, and some haven't, but only one leads to the Shine. Start by exploring the maze and have Yoshi eat every ghost in sight so they don't block the way.
If you remember the layout of the third floor, the room with the Noki couple is just to the left of the pool. So in the attic you need to follow the left wall from the hole you came through. You end up going a corner too far and then doubling back to the one you want, but you end in a room where you can crash through the floor into the pool. Now the Shine is yours to collect.
Episode 4: The Secret of Casino Delfino
- Objective: Play some slots and finish the level in an obstacle course.
Talk to the hotel manager and go inside. Then Talk to the Pianta on the left after passing the front desk to get into the casino.
There are several games in here, but for now you want to play the two large slot machines until you get three 7's. On the machine on the right, the spinners nearly always land on the same thing. So if you get one 7 then the other two will be 7's as well. You still have to keep spinning until you get a 7 though, so collect the coins and defeat the Boos that come out until you do. Once you get the jackpot the machine stops working and it's time to try the other one.
On the machine on the left only the spinners you spray actually turn. So spray the middle one until you get a 7 on it, then spray the left and right spinners while avoiding the middle one until you get a 7 on them. This also stops working when you get the jackpot.
When both of the machines read jackpot, the curtain between them open reveal a square of 16 question marks. Spray the tiles and they flip more or less at random, but only the tiles you hit with water will flip. You want to flip all the tiles to get a picture of a Shine. It's best to start at the top row and work your way down and to the sides so you end with the bottom corners. That's because it's difficult to just spray one tile but you can control FLUDD enough to just hit tiles below ones that have been flipped or just ones in a lower corner. This still takes some patience though since the occasional splash can still flip a tile you don't want it to.
When you get the shine picture it disappears and you see a pipe behind it, so jump in to start a secret level.
You start on a platform with two sliding cubes, and of course if you're standing in the wrong spot the cubes will push you off the platform and you need to start over. There is another cube behind platform moving back and forth. Wait until that cube is approaching the platform, then slip between the sliding cubes and hop to the other cube before you get pushed off the platform.
Now ride the cube you're on to another platform. This is a bit more complicated because there are six sliding cubes, holes in the platform, and there is an added danger of being squished between two cubes if you're between them. If the two blocks in front are coming toward then immediately jump to the left so you don't get pushed off. If not then stay put until they start coming toward, then move to the left. While the front blocks are moving toward the front edge, sneak behind them and grab the 1-Up on the right side of the platform, but don't hang around because this is a good place to be squished. Now head left and then to the back of the platform where the blocks are relatively easy to avoid. Hop onto a cube behind this platform to carry to on to the next obstacle; this one rotates so you have to keep moving to stay on top.
Now you have four blocks that move from side to side, but all you have to do is jump from block to block until you get to the last one. Then comes one of the rotating beams you first met in Episode 4 of Ricco Harbor. There is a 1-Up above it but it's difficult to reach so you're probably better off just moving on. There is one last cube to ride and it rotates in complicated ways so you have to watch carefully to stay on top, but it takes you to the Shine in the end.
Episode 5: King Boo Down Below
- Objective: Defeat King Boo
Get into the casino as in the previous episode. The manager mentions something about strange noises being heard in the casino so it's actually closed to the public.
This time the game you're interested in is roulette, but one of the colored areas on the wheel is purple instead of green or red. Ground pound it and the wheel lowers you into the basement where there is a larger roulette wheel and King Boo appears ready for a fight.
Episode 6: Scrubbin' Sirena Beach
- Objective: Clean up Sirena Beach
The electric goop is back! You talk to the manager automatically at the start and you get three minutes to clean it up. Use the spray nozzle for most of it (the Hover Nozzle is much slower), but you can throw the barrels to get large areas. It may also help to hold down 
and tap 
to produce a wide spray of water. Don't worry about getting every little drip; it's enough to get the larger patches. When you're done, talk to the manager again to collect your Shine.
Episode 7: Shadow Mario Checks In
- Objective: Chase down Shadow Mario
Shadow Mario is causing trouble in Hotel Delfino! Squirt him before he gets away. Watch out for the Boos, because they disguise themselves as Shadow Mario. The only difference is that the boos are a slightly lighter colour.
Episode 8: Red Coins in the Hotel
- Objective: Find the Red Coins
Hit the red switch in the hotel. You have five minutes to find all the Red Coins.
