Logical explanation as of episode 12
Anubias has only used Horridian. (except for Iron but I doubt he will be seen again)
Ben has used Bolcanon and Horridian, but Anubias has not used Bolcanon.
Jack has only used Krakenoid.
Robin has used Krakenoid and Bolcanon.
as of episode 12. It would be really weird if I turned out to be Shrek. 23:00, May 12, 2011 (UTC)
