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: Through a sea of green and islands of brown, leaving a crystal path behind, safe inside a spiral cave, preparing to come out again. What animal am I?
