Have you ever?
I nearly have (but never really would, outside an accident, which has happened... controllers are expensive!). So many times. Especially in Kingdom Hearts. Especially the Deep Jungle World.
I love Kingdom Hearts, and I love the story of Tarzan (both the Disney version and the original story by Edgar Rice Burroughs [I only liked the first three books, though. Everything after that got a little too fantastic]), but I am so glad that the (unfortunate) legal issues surrounding the Disney movie (and its use in the first game) caused the world to no longer be allowed within the KH Universe. Deep Jungle is one of the most annoying KH Worlds ever.
(If you're interested [probably not XD]: During the time Kingdom Hearts I was released , Tarzan was still usable by Disney [The movie is from 1999]. Shortly after that, however, Disney lost the rights to Tarzan.)
