I picked up this one at a LFS. They first thought it was a torch. Then it expanded. They never saw one like this. It can get long tentacles like a torch but way to fat. It also has some little dots tips like frogspawn but on a few tentacles. Some of the tentacles are fat have thin portion them a bulbous top portion as you can see on top left tentacle at about 9o'clock
. It seems each tentacle looks different and changes the way it looks
