During Bobsterfest, the Burger of the Day changes from "One Fish, Two Fish, Red Fish, Hamburger" to the previous day's "Something's NOT Fishy Burger (100% Beef)" and back before disappearing altogether and returning again..
Bob's restaurant is trashed as a result of Bobsterfest this all could have been avoided if he had closed the restaurant because of the hurricane.
If there was a hurricane approaching then Mr Frond would have closed the school and sent students home for their own safety.
