Super Mario Sunshine/Sirena Beach blue coins

There are thirty coins to be found in Sirena Beach. Some are outside the hotel, some are inside, and a few are in the casino. Since you can't enter the hotel in every episode, and only enter the casino in two episodes, location is important when you select and episode to find a coin.

Visible, outside (x3)

Ocean floor

Go to the left end of the beach and keep following the cliff to the left until the water starts to get deep. Dive and look around for the coin that's on the ocean floor. Available every episode.

Cabana

Head toward the hotel and look under the roof of the cabana on the right to find a blue coin and a gold coin. Hop on the bar and hop again to get the coins. Available starting episode 2.

Hotel ledge

Go around to the back of the hotel. There will be a blue coin sitting on a ledge one floor up. To reach it, back-flip into the wall behind the hotel and wall jump toward the hotel, then hover to the ledge. Available starting episode 2.

A blue coin is near the start point. Go straight and there is a standing block in front of you. Squirt it from the other side, and there's a blue coin!

Before you enter the hotel, spray the fires surrounding the hotel and one of them should have a blue coin.
