I am the only thing that always tells the truth. I show off everything that I see. I come in all shapes and sizes. So tell me what I must be! What am I?
I'm as plain to see as black & white. I prefer to roam about at night. Just don't attack or startle me. Or odiferous emissions may result yousee. I'm an omnivore yes it's true. But what's my name tell me do?
