Quinn's Q&A Info
"Sarge and his minions come from the Land of Munchmore. Not much is known about this mysterious land that is populated by all sorts of wild, semi-intelligent food. Professor Fitz seems to think that it is a parallel world, a sort of alternate dimension. It appears that the only way to travel between worlds is through strange portals.
When Sarge kidnapped the customers, these portals appeared within each of the apartments above Papa’s Pizzeria."
Papa Louie: When Pizzas Attack!
Sarge's first appearance is when the player enters the pizza box on the roof of the apartments above the pizzeria. He sprinkles some pepper into two pizza boxes, turning them into Pizza Monsters. Then Papa Louie appears in a room with Sarge.
Sarge has 7 hearts and is immune to Papa Louie's attacks. Sarge stands on a raised platform and drops down after throwing three pepper bombs.
The player must hit a cheese ball (produced by one of the two Pizza Monsters) towards Sarge to freeze him in place, then throw a pepper bomb at him in order to defeat him.
