I overheard some scuffling and it turns out this young man was PLOTTING. He climbed the black flower pot, slid down on TOP of the hollyhock stem, and pinned it down proceeding to EAT it. I'd say that was rather well planned!
Haha too cute. When I first got my guys, they seemed to coordinate an attack on some purslane I had in the enclosure. One boosted another; the boosted knocked a stem over and both happily had their own stem to munch on. The plant lasted a whole 5 minutes. I'm glad I'm not the only one with an evil genius tortoise.
