[Day 7] favourite evolution line - Gastly, Haunter, Gengar. I remember being amazed by the fact that you had to trade a haunter to evolve it when I was little, but even then haunter was cool enough without evolving!
Gengar - 094 - It hides in shadows. It is said that if Gengar is hiding, it cools the area by nearly 10 degrees Fahrenheit. Hiding in people's shadows at night, it absorbs their heat. The chill it causes makes the victims shake. @PokeMasters
