Fungus Among Us

Tony Amoire was ready for a hard weekend working at Badger Pizza keeping the masses fed before the big game at UW Madison. Little did he know that things would go awry when he picked up Doug Bliss on a trip to the grocery store to pick up needed ingredients to get through the mad rush that was coming.
Carrying an arrestable amount of drugs, Doug hides a baggie full of 'schrooms in the mix of portabellas Tony had just purchase when they are pulled over by the police on the way back to the restaurant. Unable to get the 'schrooms back when they arrive at the restaurant. Doug lets Tony head into work where the 'schrooms are distributed to the city through dozens of pizzas throughout the night.
After work, Tony heads home not knowing that when he wakes up the world will be a different place. Mushrooms are growing everywhere, and every living being who ate the pizzas during the night had changed into mindless fungus covered beings with a taste for destruction.
Can Tony and Doug stop the mushrooms from taking over the city before every living creature is changed, or will they fall to the fungus that was unexpectedly released upon the city.
