cookies or glittering jewels?
you only need a total of 12 cookies (to feed the pigs in step 3) and a total of 6 glittering jewels (to make 1 cane in step 6). no need to keep/buy more than that.
i have sold all my cookies and jewels in case people don't get enough from deliveries or from after mining 10 times, respectively. but yeah, it looks like this event is going to be a lot less stressful now that we don't need to keep making the same crafts over and over and over and over again.
