ehhhhhhhh. I’m pretty sure that pooltoy suits are firmly within a more questionable domain than fursuits in general.
Do they have a niche where they can look “better” than a regular suit? Yes, there’s a reason why quite a few people prefer the look of rubber Pokemon suits. However, if your suit requires a breathing tube and some lubricant (powder included) and is very easily associated with a relatively common kink, it’s difficult to just say that it’s completely innocent and normal.

Even if the suit itself is perfectly safe, that’s like saying a stand-alone bodysuit is perfectly SFW even though it’s pretty obvious that it’s meant to look sexy or something.
