Thank you, Carol! It sounds like the Dragon Fruit plant isn't the best option for me in my zone then. And I already have critters that 'crawl' around here...I don't want to wake up one morning to a cactus that thought my bed was cozier than the pot I gave it.
In all seriousness, though, that's really interesting that they can move themselves like that! Sorry it was such a PITA to remove, but it's neat that you had one. Did you get fruit from yours?
