Slime Girl-shaped slimes. A recently discovered monster girl species. They lack social awareness and are ignorant due to their species' lack of culture and history, but they are exceptionally fast learners. They are as pure as water and capable of taking on any color and form. Though their body size changes with the amount of water they absorb, when they absorb too much water at once, they become diluted and lose their ability to maintain their form before dissolving entirely. They are technically omnivores, but they can consume anything by absorbing it into their bodies and dissolving it.

Red slime Compared to normal slimes, red slimes are more acidic and volatile, and their bodies contain more digestive juices. They are smaller than standard slimes with aggressive personalities, and are known for their acrid behavior and remarks. It is believed that they developed acidic bodies capable of dissolving just about anything to adapt to life in environments with little edible matter.

Green slime A poisonous slime. Due to the toxins in their body, green slimes bubble, and they are always surrounded by floating bubbles. It is believed that they are poisonous because they live in forests with many other poisonous animals and plants. They subconsciously sprinkle their conversations with venomous remarks. Perhaps due to the water-soluble poison in their bodies, they have trouble holding their form and are incapable of maintaining a complete human form.

Black slime Slimes that have turned black because their homes were polluted by toxic waste. It is impossible to determine their original color. Though they often make dark and satirical comments on society, they are not careful with their word choice and do not generally understand what they are saying. They are extremely violent and hostile towards humans.

Pink slime A rare slime that lives in flower fields. They consume nectar and soft flower buds, making them give off a sweet nectar-like scent. It is unknown what they do when flowers aren't blooming. Because they are able to effortlessly acquire nutrients, they are very upbeat and optimistic. Their diet of flowers, which plants use to create offspring, makes their own thinking lewd as well, and they are in heat year-round.
