Ok, the last post in this thread ihas been written 7 days ago and i don't know if i got 2 bb-5 by chance or if the devs have rebalanced...
All music blocks today i received by clearing barnacles, maybe that could be a hint. Barnacle and jellisacs give different items than normal trees. I have never received antidote from a tree but several times from a jellisac.
Maybe this helps to stop the insane prices for bb-5...
@TaDa: (sorry if this is a bit off topic) The link you provided offers a different definition for that badge than the one on the acheivements page. Is the one on the wiki outdated or do they know a secret?
I've never found one during all my herb growing, tree tending, and chicken squeezing. But I id purchase one from an auction a while ago to complete my set as it was the only one I didn't have.
just got one....mine was also from tending a patch. i deliberately killed all the trees in my garden so i could tend the empty patches over and over, didn't take long to get the musicblock.
