Experiment- Casualties: Unknown

Experiments are completely covered in black fur, save for their orange tipped tail. They are 5-6 tiles tall (around 1.5 meters, or 5 feet). They also have other animalistic characteristics such as digitigrade legs and pink paw pads on their hands and feet. Their hands have only 4 digits with opposable thumbs.

Seemingly, experiments have an orange, bioluminescent sclera, with a black pupil.

They also appear to have 3 soft spikes (2 on top, 1 on the bottom) jutting out from the back of their head.

The experiments also have yellow blood, seemingly made mostly of unknown chemicals, rather than typical red blood. In addition, they do sweat as a method of cooling, unlike other furred mammals. This is likely because they possess human DNA.

Despite differences in age and recorded height, experiments are all the same height. Almost all experiments sent to the planet have a chip installed that allows them to see and visualize their current health status, including things such as their exact blood volume and progression on any infections. Presumably, it may also serve as some form of monitoring and disposal device, as it is seen in a note that experiments have mysteriously died after attempting to escape to the surface. This also serves as an explosive when giving up prematurely during a run.

Experiments have 6 slots in their inventory by default. This restriction can be bypassed by putting items into containers. If an item is put into an experiment's mouth, they will be unable to speak properly, as if they are disfigured.

It is said that experiments are a hybrid of a "human, fox, and a rat." The Experiment is also described as "canine" and can make dog barking noises. When depressed, the experiment may refuse to perform certain actions, actively speaking in the second person. This may imply that the player merely influences their actions, rather than playing as the experiment. While seemingly lacking knowledge of many common items, creatures, and concepts (e.g. horses and shovels), experiments manage to have a large vocabulary of common swear words, which they utilize often when in distress. The maturation rates of experiments seem to vary wildly; at least in terms of height, with specimens as young as 10 years being up to a foot taller than a specimen of 19 years. All Experiments are right-handed.

Expies have a strong sense of loyalty, just like dogs or foxes. This Expie is female and 21 years old. if she were to start licking herself or others, she will give a "mlem" with every lick, whether she is licking to show affection or for grooming. She is very affectionate after a while. her only possession is a red scarf. designated as Experiment 934 by the scientists. not the brightest or best with words.
