I have an idea about an alien/sci-fi theme could be perfect for this area. Tqirling toadstool could be rethemed to an alien saucer of some kind, frog hopper could be turned into something revolving around the moon and zero gravity, gallopers most likely would be removed from the park and even though the it has just undergone TLC, cuckoo cars driving school could be rethemed into driving either rockets or a dune buggy across the moon
However, the two main rides in this area will be the current C&TCF building and the 4D cinema. The replacement for C&TCF could be a journey through space travelling to different mystic worlds eventually ending with the scene which was home to the glass elevator as a rocket launching off a planet and returning to Earth
The 4D cinema could be an adventure in space loosely revolving around a crashing alien ship crashing into the 4D cinema building. Due to this, there could be a large UFO on top of the building incorporating the queline and building itself into the film playing inside the 4D cinema.
The area itself will involve lots of green goo and craters which will immerse the guests into the new area and perhaps have lots of different aliens around the area too so that the younger guests can get pictures with them. Please leave your opinion on my idea
