Card Trivia:Crystal Beast Ruby Carbuncle
- This is one of the Cover cards of Duelist Edition Volume 1, Precious Pack Volume 2, and Duelist Pack: Jesse Anderson.
- This monster appears in the artwork of "Crystal Bond", "Crystal Flash", "Crystal Conclave", "Golden Rule", "Rainbow Path", "Trap Strap", and "Ultimate Crystal Magic" (in crystal form).
- The name "Ruby Carbuncle" is a double pun, since Carbuncle is also a type of gemstone, as well as a mythical creature, alleged to be seen in Latin America. Legends say the Carbuncle has some sort of jewel on its head.
- This card's name and appearance are similar to that of Carbuncle, a recurring summon in the "Final Fantasy" game series, in where Carbuncle is also known by its Ruby.
- In Yu-Gi-Oh! GX Tag Force 2, this monster can be seen jumping on the lower right hand corner of the loading screen.
