Dredging a lake can be fun!

Hosaigo - Hose Pokemon
This Pokemon is able to disguise itself as a common garden hose or piece of rubber on the side of the road, and is often picked up by street cleaners or deposited into the trash. As a result, it often has a slight odor about it.

Drejaigo - Cage Pokemon
The cage on this Pokemon is meant to protect itself against any large debris that might hit it while it sits on the bottom of lakes and rivers. However, sometimes small fish will become trapped in the cage, and the light will begin the flash as an alert to its trainer.

Dranaigo - Dredge Pokemon
The pipe that sits on the inside of its tail cage is used to suck up water from a source, and store it in the red water tank on its back. It can carry up to 60 liters in the tank in case of a drought.
