Greetings Ladies and Gentlegerms,
I am back to play some games and melt your mind. Apologies for the lack of riddles but the flying rodent got me good this time and I had to get some medical attention before I broke out of Arkham.
So you all know the rules - No Cheating and have fun!!
Who is ready to play some games with your pal, The Riddler?
I am full of secrets, and only when you find them do they become clear…
I am filled with animals, foods, people, and anything you can think of, yet none of them actually exist within me.
I can have many names, but none of them I go by; call me one and I will never even hear your words.
I can strengthen your mind, and sharpen your skills; yet when you are finished with me I am completely useless.
What am I?
