If we get the upgrade, I don’t want the mosasaurus. I think the hype around the beast is weird and that the scene in Hollywood sticks out like a sore thumb since the only screen dinosaur in the whole ride.
Instead, I want an aviary. Have the boat go through a low, caged tunnel lined with thick trees. Above, forced-perspective pteranodons swoop around the top of the (practical) cage. Suddenly, a full-scale pteranodon crashes out of the trees onto the cage right above you. It ties into both Park and World, is entirely practical, and gives Orlando an incredibly unique, scary moment.
