Actually two questions.
The first: is this tuber coming out of dormancy?
I don't recall the little pink-purple cone being there before, but I also haven't paid a lot of attention to the Amorphophallus konjac since unpotting it last fall. So I'm not sure if this is new, or just something I've failed to notice for several months.
The second question: is this thing on the bottom of the tuber an offset I can divide off, or is it something else?
I ask because when I went searching for pictures of offsets, it looked like several small offsets is the usual way of things: I couldn't find pictures of any single large ones. Also it's sort of weird because I think it shrunk? Or else the parent tuber grew during dormancy. Which doesn't make any sense. Here's what it looked like in October:
