Candyjin are a product of design, originally, accidentally created by the ‘VooDoo Nurse’, this one here-

She was working with icejin DNA she frequently makes genetic experiments, and during which in the process of dropping the sample one clumsy assistant dumped what can only be described as a heart-stopping quantity of sugar into the receiving vat, resulting in the sickeningly sweet monstrosities known as Candyjins- though initially a blunder, the Nurse concluded that the results are successful. 

All Candyjin are either developed by the Nurse, though some, very few, are born through reproductive means. Most are native to Earth, the Nurse’s base of operations, though if they pass her psyche evaluation they are permitted to leave and do as they please. 

Candyjin are based/themed after anything and everything sugary. That includes Candies, Desserts, Soft Drinks, hell even the plant Sugarcane. If it has sugar, it’s fair game.

For the most part Candyjin are indistinguishable from “normal” Icejin, most can seemingly “pass” as normal, wherein most would believe them to be garnishing themselves with sugar perfumes. Others, like Cotton and Jelly, have exterior qualities that would give away their sub-breed. 

Anatomically speaking, their insides are quite literally candy. Even those that “pass” would not be able to hide it if someone cracked their chest open. Now, Candyjin can either pertain to one theme, or be what is referred to as a ‘mixed bag’, where their organs are a wide variety of candies. Kind of like NegaKuura-

Similarly to Icejin, they are quite resilient. Candyjin are known to be able to survive intense physical trauma, well, for longer than most other species. Most Candyjin could survive as nothing more than a head for a month or so.

This is where the Nurse comes in- she will often replicate bodies and organs for her specimen- and she will often ‘resurrect’ ones that she isn’t able to get to in time

However, they are not able to eat anything besides sugar. There is a ‘grey’ area of food that they can consume without worry, milk, bread, water, but other things like meats and most vegetables would turn to bile inside their bodies and poison them.
