RESULT: A dog (pit bull is a breed of dog).
I'm small and sometimes worthless. I sit there and look at you as you pass me by. I cannot move but I wish I could. If I'm found, it's a good thing but only if I can see you. What am I?
I come in different colors, sometimes I am hot, sometimes I am sweet, I’m sorry I can’t answer you because even though I have a bell it doesn’t ring. What am I?
I never stop running even when I stand still. If I am formed by joining two identical bodies together, can you guess who I am?
