Vanilla the Rabbit is a very motherly figure who has been thrust into a world of military law and order due to her daughter being whisked away by the government for her own safety. She's a minor character who doesn't get many lines and is primarily used for comedic relief or short exposition.

In this episode she has had to get changed into some clean clothes provided by the military, clothes she isn't typically known for wearing as her usual style of dress is more akin to that of victorian England styled dresses.

She needs to exude motherly energy with her dialogue, very grounded and down to earth as well as mature yet also be able to pivot to creepy, sinister levels of overbearing-ness when the situation calls for it (a running gag in the series is that she can intimidate people simply by looking them in the eyes and turning into a sort of motherly demon-esque character).
