As you make your way through the first island you will come across Wayne up to his head in sand. He will tell you to find four of his pups to help hurry him out.
There are two paths leading left and right from him. Go down these two paths and you will find the four pups. They are not too hard to find as you follow the paths and defeat the enemies in your way.
Once all four have been found return to Wayne and he will be dug out by the pups. Ending the night and taking you back to the ship. So if you have left any Imparite Stones make sure pick them up first or they will disappear.
