"Compassfish know where they are at all times, orienting themselves with the planet's poles using the gland on its adipose fin. They use this ability to travel the whole world, then back again."

Swim Upstream Special Move (Normal Form)
Compassfish begins moving  from the rear left to the rear right one space per turn. When it reaches the farthest right space on the field, it will transform.

Last Stand Special Move (Breeding Form)
Compassfish slashes the foe with its sharp claws. The more damage it has taken during its journey upstream, the more damage this move deals.
