Sand Dollars
To unlock certain items you need to find their associated Sand Dollars, three can be found in each level but there are also a load in the Morro Bay hub world too.
To help your search you can build and activate the "Sonar Central" building in Morro Bay after completing the level "Touch Pool Rescue". It will put a purple dot on your radar to mark the location of a nearby Sand Dollar.
