"A mean anti-grandma to vomit more cookies. (Do not put in contact with normal grandmas; loss of matter may occur)"
If you're talking about wrinklers, here's a hint. Leave them be. Let them stay all day. Then at the end of the day, pop em, and you'll gain back more cookies from killing them than they ate. You can increase your daily cookie count by massive amounts, I got to the point where each popped wrinkler was giving me 2 quadrillion each, which was about the same about I earned normally, meaning I multiplied daily production by eleven times.
Exactly, thats the point. Each wrinkler subtracts %5 of you CPS, regardless of what your CPS is. But when you pop them hours later, you'll earn back all the cookies they ate, except with interest. You can actually multiply your daily cookies by eleven times just by waiting till the end of the day to pop them,
Umm, golden cookies will become scary cookies, which have negative affects and look like jack-o-lanterns. Don't click them.
