Extremely Obese Expie

Experiments (called "Expies" shortly) are completely covered in black fur, save for their orange tipped tail. They are around 150-160cm. 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. 0B361T5 in other hand is unique; it is an Extremely obese experiment, 780lbs 160cm male at the age of 18. ~90% of his body is engulfed in layers upon layers of fat, weighing him severely down.
