What is this on the type of my green slimer?

I got this Green Slimer from my LFS last week, and it has had awesome polyp extension since I got it. Recently I noticed that at the end of each branch there seams to be an extra big polyp that I have not seen on any other Green Slimer. Is this a problem that I should fix or is it normal?
