Did you figure this out? I tried doing in sandbox mode and couldn't get it, maybe it's only achievable in one of the other game modes? bugged? Something else? I also spammed the milk increase, is that why? Am I supposed to let her expand naturally?
when you are on the end screen of sandbox select keep playing then you can make her even bigger
Ooohhh ok thank you, I didn't realize there was a difference between try again and keep playing.
