Be careful what you wish for.
By the way, my experience with rabbits tells me that thrill-seeking is the last thing they would ever do for fun. They're naturally anxious creatures and if they get scared enough they can just have a heart attack and die. Even being out in the open worries them.
Yep, rabbits don't like surprises and prefer consistency in their lives, to a degree. They won't die from every single loud noise, but, generally speaking, it's never a good idea to scare pets that are prey animals in nature.
Also, if a rabbit feels truly content and safe they'll do something called a "Bunny Flop". It honestly looks like they've died, but they're just showing that they feel safe enough to completely let their guard down.
