• This card has non-WATER counterpart: Eisbahn
  • The monster featured on the card "Stumbling" is "Gagagigo".
  • "Gagagigo" appears to be stepping in the jaw of a skeletal "Berserk Gorilla". Berserk Gorilla is destroyed if it's faceup in defense mode, so this card would destroy it.
  • The valley of skulls he's walking through may be related to why he became so determined to stop "Invader of Darkness" that he was willing to corrupt himself with cybernetics and, later on, truly lose his heart to the darkness - a common arc for characters who base their quest on stopping a figure of evil.
