I don't know about the rest of you guys, but I've been really excited to get all the musicbox cheevos by myself, even it's meant squeezing chickens to death. Up until recently I had been held back by green-4, blue-5, but through some magic mojo I got both drops in one day, both from actions I've performed fairly regularly.
I have one last musicbox trophy left, and it's the XS collection. My question is this: what actions cause an XS-4 drop??
Things I've done (i'm primarily a basic resource auctioneer so I've done some of these things hundreds if not thousands of times):
-petted, nibbled piggies
-squeezed chickens
-petted, watered, harvested all types of trees
-scraped barnacles
-harvested jellisac
-(edit) harvested peat
-watered, planted, harvested crop plots
-mining
-grinding
-smelting
-making ingots
-test tubing
-beaker-ing
-using test tube/beaker
Things I haven't done:
-everything related to herbs, potions, and tinctures
Any info/stats on other musicboxes for other interested parties also welcome! Personally, I get a bazillion XS-1 and XS-3 drops from trees.
