Royal Crown Malort
From Blaseball Wiki
Royal Crown Malort is the official drink of the Chicago Firefighters. It is also commonly referred to as "Butt's Special Stuff", as it is a triple combo of RC Cola, Malort, and hydrant water. It can only be drunk from a fire hose at full blast.
The Fire House has hoses strategically placed around the stadium. Whenever the Firefighters hit a home run, Royal Crown Malort is sprayed on the masses below in celebration.
Occasionally, the Firefighters will drive around in the official team Firetruck and spray Royal Crown Malort at pedestrians as it travels throughout Chicago's streets.
