Broccoli is a healthy vegetable that seems to be a major part of the Rhyboflavin economy. Virtually every shopkeeper in the town square farms and sells it. Vambre and Prohyas' own father is a broccoli farmer, and he tries to convince his children to return to the broccoli farm several times in "Potion in the Ocean." During "Bad Bad Cop" several townspeople form a mob that leads to Princess Zange's castle to complain when a pirate from Keelhaul steals the entire town's crop of broccoli. Hot broccoli nuggets are the one Slug Burger item that Prohyas won't eat in "Working for Scales." In "Cleanliness is next to Grupliness," Fud buys a crop of brocolli tainted by Grup's terrible odor.
