I see all these achievement / upgrade ideas, but nothing for the real point of the game, the cookies!
IF you have suggestions, put them here and use a format that is easy to read, or the one below:
(Name of the Effect)
(What It Does)
(Duration of Effect) (calculations with Get Lucky, which doubles cookie effect time, are accepted)
(The %Chance of it happening)
(Special things about it, requirements for the effect to happen, or more here)
Here is one effect using the format, for reference, that i have come up with myself.
Nightmare Lure
Gain a random amount of 1-5 wrinklers added to your big cookie, if the required slots are open.
Instantaneous effect
11.0% chance of occuring
