Polteageist's shiny changes it from cyan blue to pink. Part of me wishes it was purple to look like Mrs. Potts from Beauty and the Beast. If I didn't have a Ceruledge on my Violet team then I would have used this pokemon.
Also I drink green tea almost every morning because I dislike the taste of coffee so much. In fact when I drank it this morning it looked more darker than usual, and I felt as if a voice was telling me to drink more. I think I will go do that.
