Trivia

 * Although never indicated in the game, this is most likely a set of billiard balls which are known for being used in professional tournaments. This is inferred by the fact that the 4th ball is pink instead of the more common purple, due to the color being more distinguishable in televised events.
 * With the exception of the Sphere of Truth, all treasures in this series are used in the fifth challenge in the Trial of the Sage Leaf. The Sage Leaf refers to them as "dragon jewels".
