#154 Slowshin (Psychic/Electric)

Slowshin evolves from Slowpoke starting at level 37 when there is a Chinchou in the party.

Biology:
Every trainer is familiar with the symbiotic method by which a Slowpoke is able to evolve into a Slowbro with the help of a Shellder. In the Belgica Region, Slowpoke has many more of these symbiotic relationships, which results into different evolutions.
Some Slowpoke are known to like the taste of Chinchou. These Slowpoke are known to continually dive deeper in order to eat their prey. They're able to accomplish this feat by emiting a soft light from eating all of these Chinchou. The result is a new evolution: Slowshin. Slowshin aren't the most cunning predators, but their Electric capabilities make them some of the scariest Pokémon to encounter at the bottom of the sea.
