There would be some restrictions though, it needs to be really small and waterproof. And not fragile. Some spaces you need to crawl through are really small, even some chubby people can struggle.
And there is actually three levels, -1 (op pic), -2 which is unmapped (afaik) and you need to crouch a lot. And then -3 which is actually entirely an underwater area.
