While on the subject some others that I think would make for some good additons:
Automated track system for the animatronics, similar to what would be used for the transport rides/coasters, only instead of it being a ride it would be something to add some decorative elements that can follow the people on the ride.
For example: An anamatronic shark, which can roll along just under the water with its dorsal fin cutting the surface, but able to pop up to scare the guests as it's track rises up along side the transport track, only for it to dive under the water and go under the ride track to pop up on the other side...
Other tracked animatronics can include Dolfins, Sea serpants, Rowboats with pirates rowing along, ghosts, knights on horseback and whatever else the Devs imagination can come up with.
I'd also like to see some Dragon Animatronics with at least one that breaths fire...(Which I figure would be more like the Kraken...
