One full week after it had appeared, my third tentacle had grown to the same size as my other two. At this point, if I wanted to, I could stand on all three tentacles, and be a tripod. I was eventually able to walk on three tentacles as capably as I was on two, and could easily switch between walking on three and walking on two if I needed to pick something up with one of my tentacles. It would have been weird to say, but I had actually gotten used to the things. For the next few days, it had seemed that all my tentacles had essentially ceased growing.
