I know some of the,here:

the fountain
in the town

the bowling alley
on top of the pin

Maka Wuhu
the top of the island

heart of Maka wuhu
behind the waterfall

Migeuls guide plane
UM...?

nine hole hotel
the building on wedge island

crater
go down from maka wuhu

sports shark
the blimp with "wii" on it

private ialand
next to a small island(deserted island)

deserted island
next to private island

as there are 80 points and several of them have no definite or describable location, it
would be wholly impractical to list them all. additionally, if we gave you all the
answers, it would render the game pointless and take the fun out of it.

the last one i couldnt find was diving spot and it was behind private island

I cant find sweet beach i checked place its at but i can't find it!

Sweet beach is behind the firework launch zone 1.
Try hovering a little lower so you can find it.

Hope this helped!!!
