I think i got some bad hitch hikers with my LR. To think this is my first time buying. Anway what i have is a green with little bubble tips coming out of a leathery tube. When the lights are off the tentacles stay in the tube and when the lights are on they are out. I had one when i purchased the rock but now i have a second but it is kinda far fromt he first one. If this is bad how do i get rid of it ?
