Big furries, small spaces

So basically I'm trying to do something of a furry that is of a giant or abnormal size, stuck in a small space. Like inside a building or to be specific, a swimming pool. I got the basics for furry prompting but can't seem to get tags like size difference, growth or small space right. Anyone have any ideas as to what I can add. Or if there's any loras or models that can be used.
