Answer:
I have two bodies joined together as one. When standing still, I run and run. What am I?
Everyone has me and no one can lose me. What am I?
I am a protector. I sit on a bridge. One person can see right through me while others wonder what I hide.
I have fangs and enjoy piecing holes with a single bite.
I can be red blue purple and green. No one can reach me not even the queen.
Runs over fields and woods all day. Under the bed at night sits not alone, With long tongue hanging out, Resting at your feet until we go for a walk
