Slimes are exceptionally large cells. Most are have rounded bodies and move about by hopping and leaping. Their skin is elastic and soft, but regenerates quickly should it be pierced. The inner plasm will also coagulate rapidly to avoid bleeding.
Most slimes are carnivores, hunting anything smaller than themselves, though most will also eat fruits and nuts they find on the ground if given the chance. A few species are hypercarnivores and will eat meat exclusively, while others are strict frugivores.
Slimes are usually photophobic and will spend the day in caves or ruins, often hopping outside at night to hunt. They themselves fall prey to some animals.
