This is the problem when you spoon feed people unnecessary back stories. It restrains theming decisions, even if they are a cool idea like the eggs by the helicopter probably where at the time.
Sub Terra needs some kind of explanation as it would be odd without it. But Nemesis and Forbidden Valley worked just fine as a big monster, in a pit, wasteland around it, some sort of struggle had taken place. Just an excuse to make a cool rollercoaster. We didn't know what the drill/gun even was, or the shanty "kitchen" under the lift hill, or that cage by the stall turn. Even Blade and Ripsaw, just there because they looked cool and fit in. Even the original story in a nutshell just says mysterious site worshipped for centuries, alien underneath was discovered, burst out one day to feed, couldn't be contained by guns, here's Forbidden Valley.
Now we're left wondering why you have to queue to see an egg in a containment zone when there are a collection of them just outside? Are those B&M track pieces or tenticles being dissected? Why did they use a shipping container for a lab rather than a van or a porta cabin? Why did a toy helicopter land on a specific pile of fake rocks when there were plenty of decent real ones it could have crashed into? If they were dispatched in a hurry and quickly errected cheap corrugated labs, why did they bother to build one that looks a lot like the Galactica buildings only painted black?
None of these questions need to be asked if you just keep the story behind the theme loose and open ended.
