Frillish is a hadopelagic Pokémon which lives in dens about 5 miles (8 kilometers) under the sea surface. Because of this, it can cope with extremely dark and highly pressurized sea conditions. It is carnivorous; it gently floats around in waves until it can strike its prey. It makes its victim numb with the use of its poison spikes and takes it to its deep den.
