Not quite sure what you mean but here is an example of mine growing a new head (bottom right side you can see what looks like a mini hammer developing). There are about 5 of these "sprouts" around the base of mine along with the main piece splitting into two.
The 1st pic has a couple small heads and then to the right another small head ( I think ). That's why I asked if they are new arms where the smaller heads are ( at least they look like heads to me, hence the question).
