South Park: The Stick of Truth - Truth of Power Achievement

Achievement - Truth of Power
Fart on the Mayor, Father Maxi, Principal Vic, & Prime Minister.
**This is a Missable Achievement **

Here is where each of the four people is located in the game. You need to fart on each one.

Mayor - in City Hall (NOTE you must use Cup A Fart for the fart to hit her)
Father Maxi - on a bench in front of City Hall
Principal Vic - in the Community Center (must progress in the story far enough)
Prime Minister - *missable* found in a cave in Canada. If you don't fart on him here, he's gone and you'll have to start all over

The achievement should unlock after farting on the Prime Minister. It is highly recommended to use the Cup A Fart on every person listed above to ensure that your farts count as hitting them.
