Smiley

Slime is a pet of Caesar Clown. Slime was created by gathering and compressing the poison gas that spread throughout Punk Hazard. It was kept in the Punk Hazard Burning Lands before being released.

Appearance
Slime, as its name suggests, is a big, dark gelatinous mass. It was described as being bigger than a mountain. It doesn't seem to have a form or shape, however, the mass manifests a head with a mouth and two small, light-colored eyes. It also constantly emits some kind of toxic vapor.

Personality
It seems to have no mind or understanding of its actions, as it continuously moves forward after being released and killed some of Caesar's men in the process. It knows, however, that it is weak to water and figured out a way to avoid it, by propelling little parts of itself over the body of water.

Abilities and Powers
Slime constantly emits some kind of smoke or vapor, which poisons people that inhale it or touch it. It is also very corrosive, causing great pain on its own. Despite its composition, it appears to move faster than the average person, as some of Caesar's men couldn't escape from it, despite being centaurs. Due to its large size, it is very hard to avoid or escape. Slime also appears to be immune to extreme heat, as it could freely move over the scorching ground in the Burning Lands without any trouble. It can also shoot pieces of itself in order to cross a lake or other body of water, as it is weak to water. Even though it is immune to extreme heat, setting its body directly on fire will cause it to explode violently.

History
Four years ago, Slime was created as a result of a chemical weapons experiment going horribly wrong. Caesar Clown condensed the gas from the experiment and created Slime. He then locked up Slime for three years, which brings it to present day.

Punk Hazard Arc
After more and more people appeared on Punk Hazard and caused trouble for him, Caesar eventually did not want to collect bodies for his experiments anymore and instead decided to release Slime. Upon being released, Slime immediately started to spread and move out, killing some of Caesar's men. Later on, it was seen advancing further towards the Punk Hazard Ice Lands, where it was noticed by Zoro but mistaken for a mountain.
