I think Barney being re themed to the DreamWorks Destination is a sign of things to come for KidZone. I would love to see a copy of the DreamWorks theatre from Hollywood along with a Trolls trackless dark ride (I believe one was once rumored) and maybe a play or water area. That would make a well rounded replace to KidZone."Pets Corner" sounds like a good idea for that back area.
If KidZone curse is finally defeated, it would allow them to close it for a large project post-EU without sacrificing capacity/attractions for children. FFL has enough space for the ride itself, queue, even a flat ride for a very small miniland.
