  • Suzie

Arnold's classmates and their families

  • Helga G. Pataki (her middle name is Geraldine), is nine years old and in fourth grade. She is secretly in love with her classmate Arnold because he's the first person to give her attention and be nice to her. In one episode, Helga revealed to Lila that she loved Arnold so that she could get the role of Juliet in the school play and kiss Arnold. Later in the series, Helga admits to being in love with Arnold to the school psychologist, Dr. Bliss. However, it is implied that her best friend Phoebe is aware or suspects that Helga loves Arnold as in when she uses the code word "ice cream" during conversations. During her spare time she likes to devote her time to writing poems (mostly about Arnold) and collecting Arnold's used gum so that she can add it to her shrine of him which is a work in progress. She is neglected by her parents and calls them by their first names because she doesn't think they're worthy of being called "mom" and "dad." On rare occasions she does call them mom or dad. She resents her overachieving, perfectionistic older sister, Olga. Once in a while Helga will show a very small amount of love for her sister. As in the episode "Olga Gets Engaged" when she intervenes on Olga's behalf, saving her from what would have been a bad marriage and "Big Sis" when she reveals her jealousy of Olga's relationship with Lila. Probably because of her dysfunctional homelife, Helga is an insecure person and puts on a mean, and/or tomboyish front, making her the school bully.
  • Robert "Big Bob" Pataki, her ambitious entrepreneur father, a successful beeper

     salesman. He has extremely high expectations for Helga and frequently compares her to her older sister Olga. However, Bob does care for Helga and it is evidenced in subtle ways. In the Halloween episode when Helga and her classmates dress up as aliens and things take a turn for the worst when the people in there city think they're real aliens, Helga's friends run to the water tower that they made to look like a UFO. Meanwhile Bob and his friends go to the water tower and throw a grenade at the water tower thinking it's a UFO. Bob see's the "aliens" and gets a hold of Helga unbeknownst to him and shakes her. All the while she keeps saying "Dad! It's me, Helga!" Once the water leaks from the explosion and rinses away the facial paint, Bob realizes it really was Helga and not some alien trying to play a mind game. He says "I almost hurt my own kid! I'm a monster!" And gives her a hug as well as a piggy back ride down the hill. The episode where it is very evident that Bob does care for Helga is near the end of the episode "Quantity Time." Bob has difficulty showing his emotions for Helga since she and he always come into conflict with each other and clash. He often mistakenly calls Arnold "Alfred". (voiced by Maurice LaMarche

  • Miriam Pataki, Helga's inattentive mother. There are implications that Miriam suffers from alcoholism
    Alcoholism
    Alcoholism is a broad term for problems with alcohol, and is generally used to mean compulsive and uncontrolled consumption of alcoholic beverages, usually to the detriment of the drinker's health, personal relationships, and social standing...

    , as she often drinks "smoothies", forgets things, speaks in a slow, tired voice, has had her driver's license revoked, and sleeps a lot (often in inappropriate places). However, in one episode when Bob injures his back and can't work, Miriam fills in for him. During the episode Miriam sobers up and holds down the fort. She also becomes more attentive towards Helga until she gets carried away with the job and realizes that she is ignoring Helga. Then, she quits and makes Bob return to work. However, her sobriety doesn't last long because in episodes following this one, she is back to drinking smoothies. But the viewer learns in a Mother's Day episode that Miriam was a champion bull rider and an olympic swimmer before marrying Bob.
  • Olga Pataki, her intelligent, outgoing, beautiful sister, who attends the fictional Wellington College (or in another episode, Bennington College) and suffers from perfectionism
    Perfectionism (psychology)
    Perfectionism, in psychology, is a belief that a state of completeness and flawlessness can and should be attained. In its pathological form, perfectionism is a belief that work or output that is anything less than perfect is unacceptable...

    . Bob and Miriam consider Olga to be perfect, which bothers Helga. There are times where her parents will confuse Helga for Olga. Fortunately, Olga does give Helga more attention than their parents much of the time and has good intentions. However, Helga does not receive Olga's attention or intentions very well and often tries to push Olga away and keep her distance. Olga has a tendency to view life through rose colored glasses and appears not to notice Helga's avoidance tactics nor does she react to Helga's short temper when it is directed towards her. Therefore, either Olga likes to avoid conflict since she rarely acknowledges her family's problems, is oblivious, or in denial. It is revealed in the episode "Helga on the Couch" that Olga through the years has reacted to her family's problems by being a perfectionist and keeping quiet about the situations at hand. This is evidenced in a flashback when Helga, as a toddler, interrupts Olga who is playing a tune on the grand piano. She tries to remind her parents that she has to go to preschool but is told by Bob, "Not now! Why don't you go play or something." However, she is ignored entirely by Miriam and Olga during the whole scene as well as by Bob after he blew her off. But after Olga completes the tune, she is too busy basking in her parents' attention. Whether she ignores Helga in that scene because she is being selfish and not wanting Helga to take away the spotlight or just oblivious is not established. But the viewer does learn from the flashback that the neglect that Helga has endured has been ongoing for years.
