Night Howler Serum

The Night howler serum, also known as the savage serum, is a highly potent chemical drug made from toxic flowers called Night howlers in Zootopia. It was created by the sheep scientist Doug Ramses for the purpose of using it on predator mammals.300px
==Effects==
The drug is distilled from the flowers of the Night howler plant which induces highly potent psychological effects on mammals. When introduced into a mammal's bloodstream, the serum causes the loss of higher brain function so that the victim reverts to a feral state and lashes out at anything nearby. The effect of this Night howler sickness is that essentially, any mammal reverts to an aggressive, wild, violent state that is described as "savage".
==Role in the Film==
Under the orders of his client, Assistant Mayor Bellwether, Doug obtains bulbs for growing Night howler flowers and sets up a small greenhouse for them in his makeshift laboratory in a subway and once they are fully-grown, he distills them into a serum. The serum is loaded into small paintball-like pellets and loaded into an air-powered sniper gun, which is used by Doug to dart dozens of predator mammals for Bellwether's plot in order to make prey animals fear the predators.thumb|250x250px|Nick with the case of evidenceJudy Hopps and Nick Wilde discover the serum in Doug's lab and they later learn that Bellwether is behind the conspiracy.
The farm of Night howlers in Doug's lab that are used to create the serum is destroyed when the lab is accidentally derailed by Judy and Nick and subsequently explodes. After finding out that Bellwether is the mastermind behind the conspiracy, Judy and Nick make a run for it, but they are trapped in the Natural History Museum by her and her henchmen. Bellwether shoots Nick with the serum to make him go savage and kill Judy, but it turns out that they switched the serum with blueberries and recorded her plot with Judy's carrot pen. After Bellwether's arrest, a cure for the serum is developed for the affected predators.
