Pre-Teen ScreamHey Arnold! : Season 3 Episode 12
Phoebe is Helga's best friend (and her only one so far). Their unusual friendship is the main plot of episodes such as "Hall Monitor", "Pre-Teen Scream" and "Phoebe Breaks a Leg". Phoebe often follows Helga around, writing down notes and appearing more as an assistant rather than a friend to Helga, rarely thanking her for anything. Phoebe is too shy to stand up to Helga since she's tough, mean and nasty. However, the two do care about each other, as they listen to each other's concerns and help each other out and love each other like sisters. In later seasons, Phoebe knows about Helga's secret crush on Arnold (though it's never shown exactly when or how she finds out) and is understanding of Helga's complicated relationship with her family. Since Phoebe is so kind, Helga is very trusting towards her. A running gag throughout the series involves Helga saying something embarrassing, then ordering Phoebe to forget what she just said, which leads Phoebe to cheerfully state "forgetting!"
