In this week's episode of The Penguin, a new drug called Bliss made its debut in Gotham. This red crystalline substance is a stark contrast to the Drops that were popular in The Batman, which were favored by the so-called Drop-heads. The origin of Bliss, however, has a surprisingly real-world counterpart that is both fascinating and far from euphoric. Spoilers ahead for Episode 3 of The Penguin, which aired on October 6.

Oz "The Penguin" Cobb is eyeing a major opportunity in Gotham following the death of Carmine Falcone. With the Falcone family in disarray and the city still reeling from the Riddler's bombing, a new drug is poised to change the game. Sofia Falcone takes Oz to a warehouse where Bliss is being manufactured, revealing the grow room where the process begins. Inside, hanging garbage bags covered in a fungus excrete a glistening, crimson fluid, creating an eerie, almost alien atmosphere.

Despite the dark, urban backdrop and fictional criminals, the sight is not entirely unrealistic. The fungus in question is known as Bleeding Tooth Fungus in real life, also called Devil's Tooth fungus. Scientifically named Hydnellum peckii, this fungus is notable for its striking contrast between the pinkish-white cap and the vivid red fluid it exudes. While the Bleeding Tooth is not poisonous, it is known for its bitter taste. The fluid, though not psychoactive, has anticoagulant properties, acting similarly to the blood-thinning medication Heparin. This means it's a blood thinner that looks like blood.

The growth method used in the show is also rooted in reality. Mycologists often grow mushrooms from the sides of hanging bags to maximize space. While we don't recommend sampling random mushrooms from the forest, the team behind The Penguin has selected an intriguing fungus for their fictional drug. Just remember, don't try to get high with it, and definitely don't eat random forest fungus.
