Card Trivia:Fortress Whale
- Despite the fact that it is a Fish-type, whales are mammals and not fish. Also, its tail appears to sway left-to-right like a fish's, not up-and-down like a marine mammal's.
- This monster is the only Fish-Type Ritual Monster.
- Despite being a whale, the horn on the front of its face makes it appear to be a narwhal.
- This is the only prize card Joey Wheeler never used. This is likely due to the fact he didn't receive the Ritual Spell Card required; instead, he got "The Legendary Fisherman".
