I show you all of the seasonal achievements in the game. You need the upgrade “Season Switcher” which you can buy for 1111 heavenly chips. Achievements will upgrade your milk and milk will boost your cookie production so you should try to get them.
 
 

Hint

If you got the season switcher upgrade you can buy every season you want in game and turn them on. You can`t run more than 1 season at the same time. You can get all special cookies (eggs and more) just for clicking the golden cookies, the red cookies and you can get them for destroying wrinklers. So you should run at least the first phase of the grandmapocalypse so wrinklers can spawn. It will take some time since those special cookies (eggs and more) only have a chance to drop. Every drop is at the same time you click it also a new upgrade you can buy.
 
 
Note: Labor Day got no achievements so it`s not listed here.
 
 
 

Increase the droprate

To increase the droprate of all the special things you can do more than one thing. First you can buy those seasonal upgrades with heavenly chips. They will appear in the Skilltree after you bought “Season Switcher”. You can also use a upgrade (Mind over Matter) in your “dragon-egg” to increase the random droprate and you can put the god “Selebrak” in the diamond slot in the “Pantheon”.
