I just had one about a Berry Bush, whether to eat the berries or not, I figgered what the heck lets eat!!! (was low on food was kinda hoping this was one of those "new food source" ones), turned out my Builder died cuz what he thought was berries was actually the egg sacs of a poisonous snail.

Wahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!!! Gotta train a new builder now.*sniff*
