As much as Sarena is stereotyped as fruit-loving, she has eggs and pancakes for breakfast whenever possible (along with a bowl of fruit). She often adds a milkshake and back bacon.
If Ziggy remembers the meal at all, she drinks some sort of brown beverage along with some hardtack, or else just an 'instant breakfast' shake.
For breakfast, Naffie and Queenie eat 'food' that is squeezed from tubes, or sometimes shaken from bags. The flavours are much more inventive than the textures.
Tan Ann Pan typically eats pork ramen for breakfast. Sometimes she has toast with it. On bad days, just toast.
I'm really not sure about Navian, but I think she'd prefer elaborate cheese omelettes with white wine.
