So, did you basically take the traits of the Positive Energy plane and shape it into an ooze? If I remember correctly being engulfed in this thing is very similar to being inside the plane itself. Maybe not the Filled with Life thing, but definitely your mechanics for Golden Touch.
It has alot of properties similiar, and its touch overfills a creature to bursting alike to the plane, but its got its own twists and turns... and you can sick it on folks without having to go to the plane ;D

Then there is the fact that its healing and blowing you up is its method of trying to mate with you, so thats another thing to mess with a player's mind.
