There was a song called “A Wondrous Place” in the animated Tarzan movie… I doubt there is a connection but you never know. I suspect it will be Jaladdin-centric. I also think you could be right about the potential Wonderland connection too as it has definitely been referred to as a “wondrous place” before in literature. Not sure if they have referred to it as that in either show?
Either way, “wondrous” is a form of the word “wonder”, so the potential connection to Wonderland could still be there.
