Oh my goodness I almost forgot I could ask here!! It is probably a long shot because I found these a long time ago on Metropolis grid (sad they are gone :() by pure chance because I was lost. Anyway. "They" are alien plants and there were 4 or 5 or 6 different configurations of the same roundsih shape, and when you approached they would make this beautiful alien sound. I don't know how I managed to lose them, but I did. I think we all have lost a lot more than we were able to save over the years. Which is why we love this group!! Yep, I am a weirdo so if anyone out there has these alien plants or knows where I can find them...that would make my Christmas for the next 5 years! Thanks. Happy New Year!!!
