Riddle: I purge all that is evil and keep all that is true. Unless you speak, I can delete what you said. My usefulness has faded with the use of a pen. I am usually made of rubber, yet I am not a toy. I am both pink, and white, but also blue, or green. Do not forget me, as I can be your best friend. What am I?
Riddle: When I move, I tip the scales. I am the source of many tales. Around your foot, a sign of wealth. Around a stick, a sign of health. Around your chest, your final breath. On your neck, say hi to death. What am I?
Answer: A snake. Snake scales. Snake Tail and snakes are usually the antagonists. Snakeskin is very expensive. Snakes on a stick are almost always seen in hospitals. Constrictors squeeze the life out of you. A poisonous snakebite on your neck would kill you extremely fast.
Riddle: You don't see me, unless you heat me. You don't smell me, unless you make me. You don't know I'm here, until it's too late. I have seen countless generations, and light parchment always magnifies my presence. What am I?
