Gollum Smeagol

"We're gonna dismiss his evil ways."

-Captain Sauce

Before episode 1
Sometime prior to Kevin moving to Oasis Springs, Gollum moved into a house with Psy and Mr. Clean.

In the main series
Gollum first appeared in episode one, where he was described as a "terrifying little man" . In his very first conversation with Kevin, he seemed annoyed by Mr. Clean's lessons on urinal cleaning and decided to change the topic to Llamas, not knowing that Kevin bears a strong dislike for the furry beings.

In episode two, Kevin invites him to his party, where he wears a very nice suit and dances while thinking about CDs. After the party was over, Gollum stayed in Kevin's backyard for a while. Perhaps he was searching for the precioussss?

Kevin Sauce
Kevin doesn't like Gollum's evil ways, but since he invited Gollum to his party in episode two, it can be assumed that they get along rather well.

Psy Gangnam
Gollum lives in a house that he shares with Psy, indicating that they are quite close.

Mr. Clean
While the two seem to be close, Gollum doesn't appear to like it when Mr. Clean gives cleaning lessons, deciding to interrupt them with stories of the sun and some Llamas.

Personality and Traits
Gollum is confirmed to be evil, and appears to also be quite inpatient, as he interrupted Mr. Clean's lessons on urinal cleaning. He also appears to be insane, tough that is debatable.

Trivia
-Gollum is a character from J.R.R Tolkien's works.
