Beelzejuice

Beelzejuice is an alcoholic beverage produced in Hell. It is known to be a favorite drink of the infamous popstar, Verosika Mayday, which she had been in rehab for but arranged for her release using money and personal connections without shaking her addiction. It was accidentally fed to a catfish in the human world, mutating it into a dangerous monster and causing chaos as a result.

Description
Serving as a kind of alcoholic beverage for demons in Hell the specifics of what Beelzejuice is and its properties are not fully known. What is known is that it is a form of alcohol strong enough to intoxicate the demons of Hell even with their increased resistance to physical harm. It is considered addictive, though it is unclear if this is merely alcoholism as experienced on Earth or something more unique to Hell's beverages.

Beelzejuice has additional mutagenic properties when exposed to mortal life from Earth, capable of mutating creatures to enormous size as well as making the creature much more dangerous and imbuing it with some demonic traits. This was shown clearly when a catfish exposed to the contents of Verosika's flask grew to at minimum sixteen feet tall, develop bioluminescent glowing features, and a mouth full of razor sharp teeth combined with a barbed tongue. It is unclear what effects it would have on humans, as what appears to spill out onto the crowd when Verosika's flask is thrown is not enough to trigger a response.

The liquid itself appears yellow in color with a faint glow both in its pure form and when mixed with water. It also seems to make buzzing noises, likely as a reference to its namesake.
