Bunny still hiding today after fireworks! Anyone else?

We have a free roam bunny and he usually hangs in the living room with us most of the day. Since last night when the fireworks started he’s been in the bedroom. He’s not really hiding, just hanging out on different spots on the floor. The bedroom is his safety spot for sure but he didn’t really seem bothered by them other than the fact that he won’t come in to the living room. He’s still drinking water and eating hay and pellets but using the litter box a bit less than usual today and just way more still than usual only moving from one part of a small room to the other! A bit concerned since we want to make sure he’s running around and all.

Anyone else dealing with this? Any suggestions? We tried coaxing him out with pellets and he ran back into one of his hiding places every time we tried but will eat them when it’s brought to him.
