No, nothing nor anyone will poke you, unless you poke first.
But..........be forewarned, that you will enter a cave that is notorious for bats, they are everywhere. They especially love to fly over peoples heads, sometimes flying so low, that you will feel a breeze that is created from the flapping of their wings. I am not talking one or two little bats here either. No, these are a combination of small and large bats. Mostly mamas with their winged babes. They love to dive bomb the tops of touristas heads, if they (The touristas) rile them up. Sometimes even then, the bats might still strike, like a blitzkrieg attack. But don't worry, they don't normally become snagged in ones hair.
But, when it does watch out! Because it's like smart man! Ouch!
Apart from that, a mama bat might swoop down to pull some hair from your head, to feather her baby bat nest.
But that will only happen during breeding season, which is the spring and summer, sometimes the fall too. It all depends on how frisky the bats are behaving. So, they are pretty much basic guidelines, not the actual written rule about bat breeding.
Indy fears not the bat. Well normally anyway, he does not. That's another story.
Just cover your head and that of loved ones, if you should hear (Which you will) the sounds of bats and you all should be just fine. Well again, most likely will be anyway.
Yep, to live to tell about one's experience with the bats, tete to tete with snakes, monster spiders, zombie armies with poisoned blow dart weapons, flames from possibly hades itself and rats makes for a well rounded day at Mara's otherworldly Temple.
Enjoy the Temple of the Forbidden Eye.....
