Super Mario Sunshine/Delfino Plaza blue coins

1)Go to Delfino Plaza if you have unlocked it. Get the Turbo Nozzle and go through the door (yes, you break it). You should see a block of ice. With the Squirt Nozzle, spray it until it melts. Collect the coin and exit the area.

2)The two corresponding X marks. One is on the statue leading to Bianco Hills and the other is near the Pianta who takes you to the Airstrip.

3)Same as above.

4)M Graffiti behind a crate.

5)There is a Pianta on fire! Spray him until the fire is out and talk to him.

6)There is a lady Pianta on the island. Talk to her. She wants you to put three coconuts in the basket. There is a coconut tree right next to her, so I don't know why she can't get it herself. Spray down the coconuts, put three in her basket and then talk to her.

7)There is a Pianta lady near the Shine Gate. She wants three pineapples. Get the pineapples from the shop and put/throw it in her basket.

8)There is a Pianta lady across the water. Talk to her and she wants three durians. Go to the shop. The catch is that you can't carry the durians, you can only kick it. Kick it above the wall to the next level, then kick it across the water. Put the durians in her basket.

9)There is a Pianta lady across from Pianta lady from number 6. She wants three bananas. Put three bananas in the basket (if you didn't notice, she said three bananas. There are three bananas in one bunch, So technically, she wants NINE bananas).

10)There is a M Graffiti behind the crate near the Shine Gate.

11)There is a M Graffiti behind a building on the wall.

12)Get Yoshi. There is a force field on the top of a building near the Pianta on the roof,

13)Same as 11, but the force field is on a building near the lighthouse.

14)There is a blue bird on the roof near the statue.

15)There is a blue bird across from the force field in 12. Go across all the roofs to find it.

16)Get the Turbo Nozzle. On one of the pillars, there is a small door. Go through it for a blue coin.

17)In the jail cell under the bell tower nearer to the beach.

18)In the sewers near Corona Mountain.

19)In the sewers near the center of Delfino Plaza.
