MISSABLE
The 4 people you have to fart on are, Father Maxi, Principle Victoria, The Mayor, and the Prime Minister of Canada.
Father Maxi is located on the bench near city hall for the entire game.
Principle Victoria is located at the community center which is to the right of the school.
The Mayor is located at city hall. Some people have said that shes glitched but shes not. It's just very difficult to actually fart on her using a regular fart, so use the Cup a Spell to hit her.
The Prime Minister of Canada is missable so be very careful that you actually fart on him. While in Canada you will eventually have to rescue him from a cave. Once you Nagasaki fart your way through the big boulder you will have to fight a group of animals. Once you do that make your way over to the Prime Minister and fart on him. Be warned that once you speak to him he disappears from the game so be very sure that you fart on him before speaking to him
