Card Trivia:Sea Stealth II
- "Fortress Whale" and the tornadic waterspouts from "Tornado Wall" appear in this card's artwork.
- This card's name is a reference to what Mako Tsunami called his strategy in Yu-Gi-Oh! Duel 180 (Duelist Duel 121): "Return of the Sea Scourge" and Yu-Gi-Oh! episode 69: "Legendary Fisherman, Part 2".
- This card's effect is also a reference to that, since Mako was able to hide and bring out his monsters from the Ocean, just like this card destroys and Summons them back.
- This card's artwork is based on two panels from the Yu-Gi-Oh! manga: first, the panel in which "Fortress Whale" appeared in Yu-Gi-Oh! Duel 181 (Duelist Duel 122): "Conquer the Sea!!", and second, the panel showing the unnamed monsters that would be Tributed to Summon "Fortress Whale" hiding underwater in Yu-Gi-Oh! Duel 180 (Duelist Duel 121): "Return of the Sea Scourge".
