Parapy grows inside the mouth of a fish and replaces the tongue of its host. It uses its host's body as a trojan horse, attacking unwitting prey as it swims by.
The fish that Parapy inhabits does not appear in Pokémon Sage as a Pokémon. A similar, if larger, purple fish is held by the Warm variant of the Fisherman trainer class, and is mounted on a wall in the Quaver Townice fishing shack, however.
Parapy's Pokédex entry describes it using its host's body as a "Trojan horse", referring to a legendary ruse performed by the Ancient Greeks to infiltrate and conquer the city of Troy by hiding inside a wooden statue of a horse.
Design origin[]
Parapy's tongue is based on the tongue-eating louse, a parasite that enters a fish through its gills, and destroys and replaces its tongue.
Name origin[]
Parapy's name is a corruption of parasite. It also evokes the word baby.
