The Triseraquins are ocean-dwelling creatures living on Earth.
Triseraquins are a highly intelligent species, capable of building time machines, creating elaborate disguises and plots, and building cities underwater that can sustain non-aquatic life.
They are amphibious, meaning they are capable of surviving on land or in the water. They have a set of gills along their long necks, and three antenna-like protrusions on their heads. They are also incredibly tall (perhaps twice as tall as Jack) and have large hands with bulbous fingertips. They all have UK accents; Ringo speaks with an accent similar to Ringo Star, Guiness' accent similar to Alec Guinness, and Connery's is similar to Sean Connery.
