Microsoft Paint for Mac?

Yeah, I have tried ChocoFlop. And Seashore. And Paintbrush. And GraphicConverter. And about five billion more programs. But none of them work. I need something that lets me do pixel by pixel image making, as well as a fill tool that doesn't count colors that look similar to it as the same color. Plus it needs an eyedropper tool. So, either way, is there something EXACTLY like Microsoft Paint for the Macintosh, or something very similar?
