Val/Fiona would be Willy Wonka cause they have the vibes. Liz and Goldie would be more like the Oompa Loompas cause they’re Wonka’s/the Frizzle sisters’ assistants.
The only Frizzle student I’d compare to someone from WW&tCF would be Ralphie/Augustus Gloop. Reason: Both have huge appetites. Ralphie’s always talking about food.
