Niko the Oyster - (Story 2 of 33) - One question that always comes up when talking to Niko is - Why doesn't Niko open his mouth more often? There is a reason for this. It's because Niko thinks that opening his mouth may allow demons to steal his soul. Therefor, he keeps mouth opening to a minimum.
Itchy the Swordfish - (Story 4 of 33) - Itchy wasn't always the grizzled, alien-attacking warrior that he is today. In fact, he used to be a water coloring, vegan pacifist.

Prego the Momma Fish - (Story 4 of 33) - Everyone knows Prego as the loving mother to a thousand guppies. But the question on everybody's mind is - Where did she get that exquisite scarf?

Zorf the Seahorse - (Story 5 of 33) - Some people wonder, why doesn't Zorf upgrade to level 3 food? The reason is that Zorf thinks that most foods are too rich in fat and artificial preservatives.

Clyde the Jellyfish - (Story 6 of 33) - Clyde, much like Stinky likes collecting money. Unlike Stinky though, doesn't collect money for just any lady. He is actually saving up to fianlly get his mother the operation that she needs. So just remember that every dollar left over at the end of a level might just go to Clyde's mother's operation fund.
Vert the Skeleton - (Story 7 of 33) - Some people are afraid of using Vert because they think that he is an undead product of dark occult forces and therefore may turn against them at any time. This is simply not true. Obviously, a bad skeleton would not give you gold coins. He would drop rat poison.
Rufus the Fiddler Crab - (Story 8 of 33) - Rufus started his career as a dance instructor, teaching people how to do his patented pop and lock aim routine.

Meryl the Mermaid - (Story 9 of 33) - Meryl delights in thrilling audiences around the world with her virtuoso singing talent. She has never been able to measure up in the eyes of carnivores or ultravores though. These fish view her simply as another unoriginal corporate-sponsored pop star. To her critics, Meryl would like to point out that she has never sold out by making a music video.
Wadsworth the Whale - (Story 10 of 33) - Wadsworth has made quite a comeback since his accident several years back. Hopelessly addicted to plankton and abandoned by all his friends, Wadsworth lost all muscle control one day and accidentally ate all the fish in his mouth. Since fishing rehab four years ago, Wadsworth has re-entered himself in Insaniquarium players' hearts.
