kilt, and he almost always wears dark sunglasses that he rarely takes off. Iggy is infamous for the episode "Arnold Betrays Iggy", where his classmates find out he wears pink and white bunny pajamas after Sid and Stinky discover it and he blames Arnold for it, angrily rejecting his apologetic actions until Arnold reluctantly subjects himself to a widely publicized humiliation from many of his kid and adult friends by wearing the same bunny pajamas in front of him in public; during this time, Iggy finds out that Sid and Stinky were the true culprits and tries to apologize to Arnold afterwards, but Arnold only gives him an angry look, implying that he is too angry to forgive him. In later episodes, however, there is no continuing animosity between the two as Iggy continued to associate with Arnold, implying that Arnold has either eventually forgiven him or the time has passed long enough to be as if it never happened. Brainy (voiced by Craig Bartlett) is a geek and Helga's stalker who is usually knocked unconscious by Helga without Helga looking at him. He seems to be romantically attracted to her.

Apparently Brainy hasn't told anybody else about Helga's crush on Arnold. He has the same hairstyle as Bart Simpson from The Simpsons. In The Jungle Movie, he continues to stalk Helga though he ends up helping her by retrieving her locket and Arnold's torn-up picture which Helga discarded in anger after Arnold had seemingly rejected her, giving the locket and the repaired picture back to Helga after the class had been captured by Lasombra. Having forgiven Arnold, Helga thanked Brainy by kissing him before rushing off much to his surprise and delight. Helga's locket would later play a key role in releasing the cure that cured Arnold's parents and the Green Eyes, which would not have been possible had Brainy not retrieved it for Helga. Nadine (voiced by Lauren Robinson in the series, Laya Hayes in The Jungle Movie) is a young entomologist and Rhonda's best friend. She tends to find a lot of Rhonda's more stuck-up opinions ridiculous. In the episode "Dinner for Four", she sets cockroaches free in a restaurant as a favour for Helga. This is
