I made a cookie potion and used it during a combat, then a message alert appeared with this text:

After taking a quick peek at the code, this is just the intended behaviour of a cookie potion and has no direct bearing at all.

But wait, there is more!

This code got me curious, because it's a base64-encoded string of various values - similar to the save format - and similar to the (obviously-related) Cookie Clicker save format.

First step - Cleaning up at the end (%3D becomes =, and %21END%21 is discarded - it would just be turned into !END!, to mark the end (duh!) of the code):


The above code is compatible with the current version of Cookie Clicker and results in the following game state:

Cookie Clicker: Cookie Overflow Edition

But wait, there is more!

If we decode it from base64, we get this code:


Importing this save in Cookie Clicker Classic, results in an even fancier save state, as follows:

Cookie Clicker Classic: Cookie Overflow Edition

  • It's not similar to a save data format. It has to be something different =/

  • @SysDragon It is save data, just for a different game. Updating my answer as we speak.

Interestingly enough, I found this by searching my cookie clicker export data. This is a bit late, but that's the exact format every cookie clicker save code uses. I'm pretty sure that's a cookie clicker code :D, what a fun little easter egg.

It might not be similar to a save format code, but it's 100% similar to Cookie Clicker's save format code. Not to mention the name is "Cookie Potion", that cannot be a coincidence. :P

Best easter egg ever.
