Smiley

Slime is a pet of Caesar Clown. Slime was created by gathering and compressing the poison gas, that spread through Punk Hazard. It was kept on the Fire Lands' side of Punk Hazard before being released.

Appearance
Slime, as its name suggests, is a big, dark jelly-like 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 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.

Abilities and Powers
Slime constantly emits some kind of smoke or vapor, which seems to either poison or suffocate people that inhale it. Despite its composition, it appears to move faster than an 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 Fire Lands without any trouble.

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.

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 Ice Lands side of Punk Hazard, where it was noticed by Zoro but mistaken for a mountain.
