Pacman frog is SO noisy

[bmatthews8]

His squeaking is probably him trying to dig and rubbing his legs onto the glass of your tank. My frogs do this every night as well. I don't believe Pacman frogs make a lot of squeaking sounds any other way - the croak is a very specific calling sound which mine (and others from what I've read) does extremely rarely.

Actually these are squeaks coming from him! I’ve actually seen him do it while he’s sitting on top of the dirt, he moves kind of like they do when they croak, but these are high pitched squeaks. He will even do it now when I touch his back it makes me wonder if he’s trying to croak, but he does it so often I am a little bit worried.

I'm no expert. And I've only had my pacman for a few months. But mine only squeaks when he's stressed. For example taking him out to clean his tank. My only thought would be is the substrate deep enough for him to bury himself?
