Slime, as his name suggests, is a humanoid monster with a body comprised entirely of green slime. He has green eyes (one of which is typically obscured by a hair-like patch of slime) and long arms, and he typically appears wearing a purple wool hat, dark blue jeans that are torn at the knees, and brown boots.
In "Monster Bash", he is shown to be helpful and kind, willing to heal Penelope's spider bites in spite of her disgusted comments aimed at him earlier.
Slime appears to be quite laid-back and doesn't care if his slime stains or dirties objects, as seen in "Butterfly Follies".
Slime first appears in "Monster Bash" attending Star Butterfly's party at the Monster Temple to unite Mewmans and monsters. He approaches Princess Penelope Spiderbite and tries to ask her for a dance, but she is initially disgusted by him. After he uses his slime to heal her spider bite, however, they become friends.
When the two accidentally stumble into a secret temple chamber, Mina Loveberry attacks them and captures Slime, and Penelope gets blamed by the other monsters for Slime's disappearance. Slime is later rescued with the other monsters in the end when Star, Marco, and Tom chase Mina off.
In "Butterfly Follies", after the battle against Meteora Butterfly results in the destruction of Butterfly Castle, Slime takes up residence in the Mewman/monster village of New Monstertown, and he briefly appears receiving freshly washed linens from Sir Lavabo.
In "Surviving the Spiderbites", Slime is revealed to be in a romantic relationship with Princess Spiderbite after the events of "Monster Bash", and the two communicate often via text message.
In "Here to Help", Slime briefly appears visiting his parents with Penelope in Monstertown before Mina attacks with her army of Solarian Warriors. In "The Tavern at the End of the Multiverse", Slime is among the many monsters that Mina and her warriors prepare to shove off a cliff.
When Slime first meets Penelope, she is initially wary of him and disgusted by his slimy body. After he heals her spider bite, however, she calls him amazing, and the two become fast friends. As of "Surviving the Spiderbites", Slime and Penelope are boyfriend and girlfriend, and Slime also has a good relationship with Penelope's parents.
