The Aquarpey were large green aquatic creatures with six tentacles and green skin that helped them to move on land or in water. They were able to create small water puddles of psychic resonance particles that cast a reflection of possible versions of a person's own future by tapping in to thoughts buried really deep down.
An Aquarpey stranded on a planet for centuries created such a large number of ponds that the planet became known as Pondinium adding to the attraction of such a beautiful planet, a planet that the Eleventh Doctor took companions Amy Pond and Rory Williams to visit. (COMIC: Pondnium!)
