Animals called Wrinklers, which resemble jittery leeches, live on the Big Cookie in the game.
Each wrinkler stores the total number of withered cookies and withers 5% of your CpS. When you swiftly click three times to pop them, they return 110% of what they have stored.
They lessen your passive cookie production but, if you let them be, they give back far more. The spawn rate rises with each level of Grandmapocalypse once they initially emerge.
While wrinklers lower your CpS, only passive cookie creation is impacted. Wrinklers have no effect on anything else, including clicking, Luckies, Ruins, CpS-based costs, or plants that yield a number of cookies dependent on CpS when harvested
