Relative spawn rate of Aquapolis?

Also, there are no troll doors. You have a 50% chance of getting the right door. There is no trick to troll you with, just random chance.

There are troll doors.
They were just talking about the animation (looks like it might close, but still lets you in... or even later rainbow animations).
They were not talking about the actual chance of it working or not.

The animation is a troll animation = "troll doors."
