Big Cookie

Big Cookie
The Big Cookie, also known as the "Perfect Cookie" within the game's code allows you to gain cookies via clicking, and it's also where Wrinklers and cursors stay. When you get a decent amount of milk, you can dunk your Big Cookie to get an Achievement, by making the screen smaller so the cookie is in the milk. Upon clicking the big cookie, a random cookie particle will appear based on the types of Cookies you have bought. There is also a 1/10,000 chance Orteil's face will be displayed instead of a cookie, these chances go up to 100% if your bakery is named "Ortiel" or "Ortiel".

Grandma Cookie
The Grandma Cookie, also known as the "Imperfect Cookie" within the game's code is an unused version of the Big Cookie with a grandma face on it. It is used as an example for Loader replacing. It can replace the big cookie by pasting the following line of code into console: Game.addClass("elderWrath")
