"Ah, yes - I think the last time I mentioned it in public was back during the first month of arrival. In brief, then - there's a tree in my home region called the Entree. By harnessing its power with the C-Gear and Xtransceiver, I was able to physically materialize things from the shared world of dreams and travel to other worlds."

Slight pause.

"Simply traveling to another world was enough to change my outward form; but if I undertook a mission to nurture the Entree I would be transformed completely - sometimes into a Pokemon, sometimes into a small child, sometimes into a middle-aged man."
