When you pay for flights to take you halfway across the world, you don't want to spend all of your time in the hotel room. Instead, you need to make the most of your dream vacation. And this couple planned on doing just that - which is why they booked to go diving amongst the fishes and the coral. But while they wanted to take a photo of their underwater adventures, it seems as though this censor fish didn't want bare skin in the photo.
So, it blocked the bare skin - allowing them to take their picture but keeping things PG simultaneously. We guess Dory didn't want to just keep swimming when this happened.
