Giant Skull Goldfish

Description
The Giant Skull Goldfish (GSG for short) is a quite large Goldfish, about the size of a car. It appears to be slightly translucent, due to the fact you can see quite a few skulls floating around inside its body. It's body is very orange-sicle-ish color, with darker orange spots on most of its scales. Basically, it looks like a regular goldfish, just extremely large, as well as glowing and filled with skulls.

Abilities
The only abilities the GSG seems to have is the ability to defy gravity. In all pages that it has been on, it has been floating, seemingly without help from anything else. Another ability it seems to have is to be able to live without having to be submerged in water.

The GSG has telekinetic abilities, that are shown as it lifts Joki during "Still Dreaming"

Joki
Starting on Page 58, the GSG began stalking Joki. Due to it's menacing appearance, Joki took off, with the GSG in tow. Eventually Joki ran into the hospital doors like the genius he is.

Ace
This dude totally killed this thing. Well, maybe not kill, more so, he turned the GSG into a card. Said card is apparently worth 250 of whatever currency Aisho uses.

Trivia

 * The skulls inside the Giant Skull Goldfish's head are all missing their bottom jaw, except on Page 60, where two skulls can we be seen with their bottom jaws.
 * On Page 63, a darker colored skull can be seen inside of The Fish. This is odd because it appears to be from a human, but humans have white bones.
 * Each of the skulls appear to have air pockets surrounding them, meaning the inside of the fish is hollow.
 * Also, it appears that small bubbles are coming off of the air pockets, meaning that the skulls are most likely being slowly digested.
 * The card that the GSG became when killed said "Markka" at the very top of it. Markka is "a cupronickel or bronze coin and monetary unit of Finland until the eurowas adopted, equal to 100 pennia; finmark."
