So didn't they remove him before for the same reason they got rid of Captain Jack. A few too many guests were telling him a few too many inappropriate things. Like telling Captain Jack to come back to their room and drink some rum with them?
It's not hard for me to believe that a shirtless, ripped, man in a loin cloth would hear some frisky things.
Don't get me wrong, I'm a fan of meet and greets, but I think for certain characters it would work better to see them without being able to really interact with them.
For example, let's pretend they retheme'd Swiss Family Treehouse to be Tarzan's treehouse, like in Disneyland. Then during the retheme they connect all the rooms so Tarzan can go in and out of them without entering the actual queue where guests are.
How cool would it be for the 7 people that walk through that attraction to maybe get lucky enough to see Tarzan in one of the rooms. Then when he notices the people he runs to another room somewhere else. The guests would be able to see him in his natural habitat. It would be his Treehouse after all.
I feel like I'm picturing this better in my head than how I'm explaining it.
