• This card's Japanese name, "Mother Brain", is likely a reference to Metroid, a popular Nintendo Game.

• The smaller fish seen in this card's artwork feature in the card "Fish Depth Charge". On closer inspection, it seems that they are even docked along "Cranium Fish"'s body (the blue shapes embedded along its lateral line).

• This card appears to be a stronger version of "Ocean's Keeper", having a similar color scheme to it, looking like it, plus it's effect makes it like Ocean's Keeper is growing.
