hi. i am a clue ball.
I am approximately 3 inches in diameter and made out of clear plastic.
However, some of my hiders like to camouflage me. At least half of me must remain clear however (so I can breathe) and a part of that clear portion will be showing without you having to move anything.
When you find me I will have a piece of paper inside directing you where to go to claim your TREASURE - A Glass Ball.
