Thanks for the testing Coolkitty.

The chances of finding it in a chest are not lower than anything else to my knowledge, but of the 4 Extractinators I found so far, all of them were found in Ice Biome Undergrounds. This does not means it is exclusive to this Biome, but so far the odds are leaning towards that.
