"Sto- STOP EATING LITERAL GARBAGE WE HAVE FOOD HERE!"
Slimes are small different colored gelatinous beings that resemble a cell of the human body, they move by dragging along the ground, they can not speak, and can form parts of their body into a small tendril that acts like an octopus tentacle.
Slimes are sort of like an ultimate scavenger, no one knows where they came from or even when, throughout history whenever there were creatures to leave waste behind, the slime was there to eat the waste, and even the creatures themselves when they died.
Slimes are solitary creatures, they spend little time doing anything but moving and eating and its unknown whether or not they even know what they are until they eat a being with sentience, these slimes who gained sentience don't really seem to like staying in that form, and prefer to abandon their newfound desires to keep living the lives they always have, which is eating everything they see. They are born when their parent grows too large and splits into multiple different slimes, at least this is the theory as slimes have never been observed doing this and sentient slimes can not seem to recall how they were born. Slimes do not have gender of identity naturally, but sentient slimes sometimes choose to identify themselves with names and genders.
