Poliwhirl Evolves

The ninth day after returning to the Orange Islands, sunny.

Yu Hai had been unable to sleep that morning. The moment he opened his eyes, he thought about Poliwhirl's evolution, so he woke up early. It was only a little past five in the morning; the sky was barely bright, and the sun had yet to rise.

He had discovered a method of using the environment to assist evolution. Although it could only be used on special Pokémon, such as how Magmar could melt Fire-type items to aid absorption, Psychic-types should also be able to instantly drain Psychic-type energy.

He should have thought of it long ago. Since Poison-types could be strengthened with Poison-type resources, there was no reason other Pokémon could not do the same. The key issue was still absorption.

Because Gengar and Weezing were Pokémon made of gas, they did not fear poison, so they could be force-fed resources.

Magmar was not afraid of lava and could even swim in it. Lava was greatly beneficial to Magmar. It probably did more than just relieve fatigue; it might also help with Magmar's future growth.
