What is this?

Can anyone tell me what this is, is it one of a kind. It's wooden, when you tip it, it sounds like water running. If you look close the little black dots are some sort of needle poked into wood. Must be filled with sand or something , so when you tip it it makes the noise of running water. Are these common? What kind of wood is this? Where does it come from ? Bought at a yard, said it was her daughters. It was given to her for a graduation present. That's all she knew.
