Spin-Off from Johnny the Homicidal Maniac, Squee ran four issues and followed the titular next-door-neighbor-of-aforementioned-maniac as he encounters aliens and all other manner of paranormal activity.
Abusive Parents: Squee's parents are of the horribly neglectful variety.
Anal Probing: When the wheelchair-bound aliens try to abduct Squee again, one of the two aliens goes to his parent's room and subjects Mr. Casil to this.
Pepito: Son of the dark prince, child of darkness. Some call me the altar boy of doom. Others will know me as the second coming of damnation. My mom calls mePepito.
Improbable Weapon User: At the "Defective Head Meat Institute", Johnny says to a dream-studying scientist that he dreamed about killing her with a bag of ramen noodles.
Happily Married: Pepito's parents seem to be this...despite the fact that his father is Satan. Subverted with Squee's parents, who are still together but with obvious instability between them.
Interspecies Romance: Señor Diablo and his wife (Pepito's mother) could count as this. Also, one of the Meanwhile comics features a guy forced to mate with a chicken so that his aliens captors can research human sexual encounters. To make matters worse, it's revealed that the man eventually marries the chicken and has kids with her.
Kids Are Cruel: Squee tends to be bullied mercilessly by every kid he ever meets for no apparent reason. The only exception is Pepito, who's fairly nice to Squee. Too bad he has a nasty habit of melting his other classmates faces' off, but at least he's nice to Squee.
Lighter and Softer: Less paranoia and debilitating mental disorders and serial killings than in JTHM. Ok, I tell a lie, but here it's all Played for Laughs.
Mad Eye: As per a Jhonen Vasquez production, Squee is depicted with one after Pepito blows up the school to save Squee from zombies.
No Name Given: Ms. Bitters is never addressed as such.
Ping Pong Naïveté: Closer to ping-pong innocence. How aware Squee is of how screwed up his world is and how much he's willing to do something about it tends to vary from storyline to storyline.
Toilet Humor: Tons of it. Special mention goes to the unseen man in the restaurant bathroom stall in Issue Two. Holy shit.
Transplant: The stupid, wheelchair-bound aliens show up to abduct Zim, whose teacher (Ms. Bitters) is also Squee's teacher. The horned, purple aliens are revealed in Zim to be residents of the planet Vort, which is conquered by the Irkens. The big one, however, is Zim himself, who shows up on various posters in Squee's room.
