Katina is the matriarch of SeaWorld Orlando that clearly resembles the orca in this graphic (90° bent dorsal fin). This newer built bathroom, possibly in line with the newly renovated aquarium, had multiple tiles of random sea creatures placed along the walls. I do not know why they chose such a random orca, maybe the artist was just a fan.
Nothing as unique as this if that's what you were wondering but the randomly placed, and small numbered tiles depicted typical tropical and freshwater fish along with jellyfish.
