Openable Logs

does anyone know of a log or decor that can be opened up? my frogs love to squeeze themselves into logs but I wouldn't be able to get them out easily on case of emergency, such as a prolapse. there's been a few situations already where I had to urgently get them out but they're too comfortable in the Log. I was wondering if there was a version of logs where it has hinges on the outside, magnets, something to give them the same coziness without the danger? opens like a door? I apologize if this is confusing, its hard to describe what im picturing.
