Hi speed boater,
That animated signature was made for me from some screenshots I took by one of the forum members, Captain Bluebeard. (Formerly known as TJK).
You can have such a thing, but you have to have it/make it first to put it in your profile.
And no there are no secret waters to be unlocked. As Terry said, the things mentioned here are from SS08, not SS06.
Regards,
Fred
