I won't be able to access my Planet Zoo computer for another week cause I'm out of town, but I know that the tropical pack came today and I was wondering what the lar gibbons are able to brachiate on. I saw them brachiate across the liana vines in the trailer, but can they do that with anything else? Obviously they can do that with the metal structures, but it'd be cool to see them doing that with ropes or something like that too.
