I can't really make anything out there, maybe need higher magnification or maybe it's not focused on the right thing?

Even under about 25x magnification I can make out individual cells pretty easy, so you should be able to see something unless it's a toy microscope. Try focusing past what's on that image, maybe that's just top of the glass or something. I see some more blobs of brown stuff behind it that are out of focus, maybe that is something.
