Super Mario Sunshine/Pianta Village blue coins

There are thirty coins to be found in Sirena Beach. There are two coins that appear only at night, episode 1, 3, 5 an 7, and another that appears only in the day, episodes 2, 4, 6 and 8. Most of the coins here are easy to find, but as you would expect for the last level, there are a few which are well hidden.

Visible (x5)

West lawn

Go left from bridge at the start and follow the path around the corner. There is a grassy area on the left with five wells that take you to the village underside. Check the edge, behind a small tree, to find a coin. Appears all episodes.

East bridge

Go right from bridge at the start and follow the path around the corner. Continue until the bridge crosses the stream (night) or dry bed (day), then check under the bridge for a coin. Appears all episodes.

Stream outlet

From the 'East bridge' coin location follow the stream/dry bed left to a small gate where the stream spills out when it's flowing. There is coin in front of it. Appears all episodes.

Northwest tree

Go left from bridge at the start and follow the path to the hot spring. Go up the trunk of the giant tree to the left of it and find a blue coin at the crown. Appears all episodes.

Southwest tree

Go left from bridge at the start and follow the path to the corner. Go up the trunk of the tree just past it to the crown, then follow the leaf stem on the left to the end of the leaf. There is a blue coin sitting on a little ledge to the right. Appears all episodes.

Graffiti (x8)

Start M

At the start, immediately turn around to find a graffiti M on the cliff face behind you. Wash it off to get a coin. Appears all episodes.

Pond M

Bear right from bridge at the start and locate the larger wicker structure behind a red mushroom and in front of the pond (or the dry lake bed daytime). There is a graffiti M on the front side, wash it off to get a coin. Appears all episodes.

Fruit tree M

Bear left from bridge at the start and locate the plateau with the fruit tree and a red mushroom. There is a graffiti M on the front side, wash it off to get a coin. Appears all episodes.

Underside M

Bear left from bridge at the start and locate a well to the underside next to a red mushroom. Ground pound the gate to get through. Look around for a sliding grate, climb onto it and ride to another section. (If you've completed episode 3 then you've already gotten used to doing this kind of thing.) Make a U-turn to the left and follow the grate to a swing, then drop and hover to a vertical grate in front of you. (Alternatively, drop to the swing and hop from the swing to the vertical grate.) Climb to the top of the grate, immediately turn around and hover over to the top of the grate you were just under. Hop to the section on the right, this is a ledge around the well you came through at the start. Go around behind the well and adjust the camera to look above you to find a graffiti M. Wash it off to get a coin. To get back to civilization, follow the path until it turns to the left, then hover straight across to another section. Go right and slowly go over the edge to a vertical grate. Flip the gate to the other side, the go up to the underside of the section you were just on. Ride the sliding grate here to the underside of the section with the well. Get the gate and flip it, then wall jump out the well to end up where you started. Note, the M is there even at night, though it's nearly impossible to see, so it's better to do this in the daytime episodes. Appears all episodes.

Paired triangles (x2)

Locate the graffiti triangle on the end of the wall in front of the hot spring. Then follow the path right from the hot spring to an area with lots of little yellow mushrooms. Across the path from those locate the corresponding triangle on a cliff face. Wash the graffiti from one triangle to make a coin pop out at the other triangle, then get to the other location before it disappears. The symbols are close enough together so that it should be no problem to reach the coins in time, but using the slip-slide move may help. Appears all episodes.

M by the Mayor

When you recover FLUDD in episode 3 (see the walk-through for that episode), check the platform next to you to find a graffiti M under it. Wash it off to get a coin. Appears episode 3 only.

M under the goop

Once you get FLUDD in episode 3, make your way back to the bridge near the start. Wash the section of lawn immediately across the path from the bridge to reveal a graffiti M. Wash it off to get a coin. Appears episode 3 only.

Miscellaneous washing (x?)

Rescue villager (x8)

After you rescue the ten villagers from the goop, talk to each one. The two kids just say thanks but the other eight give you a blue coin as a reward. Appears episode 6 only.
