Answer:
I am an activity dogs are very good at when a ball is thrown.
You write on me and secrets I can keep in places never seen. I spin like a top. Though stiff as a board, I'm often described like a mop. What am I?
I am a red drum which sounds without being touched, and grows silent, when touched. What am I?
With pointed fangs I sit and wait; with piercing force I crunch out fate; grabbing victims, proclaiming might; physically joining with a single bite. What am I?
Although glory but not at my best. Power will fall to me when the man who made me dies.
Give it food and it will live, give it water and it will die.
