Don't forget that Von Roo
is awake all day today. I lucked out by gaining a level. I could have sworn that the timing of your click mattered, but most of the guides have taken that information out. Regardless, I tried to time my click for the round minute, and I managed to win, so I'll take it. (I clicked at 58 seconds, right before it switched to 59.)
Oh, fun. The bags give from 1-4 of a long list of items. According to JN, there's an R101 book in the Esophagor bag, the Edna bag (along with a mirror (grooming)), the Anshu bag (along with a toy and and a food), and the Kiko Lake Carpentry bag (along with a stamp), and a wearable necklace in the Tropical Food bag (I'm guessing there's a book, too).
Those books and that stamp are going to be ridiculously expensive. Do I buy extra bags? Just buy the items? I hate doing things like treasure maps and getting items that are worth less than the map. I never seem to get the rare prizes.
