Injector MIA for Mighty Morphin' Quest

Sir Hammerlock in Sanctuary has given me the quest "Mighty Morphin,'" this quest requires me to take an item from him that is a serum injector. Then I am supposed to use said injector to inject Varkid cocoons in Tundra Express. However, I can't find the item in my inventory after I grab it from Hammerlock (if it is even a weapon or whatever), and I've no idea how to inject the cocoons with the serum. Am I supposed to have something in my inventory? What am I doing wrong? :(


Solution 1:

It's not an item in your inventory. Just 'use' the cocoon when they turn into one.
