Mine is Grumpig. I like this psychic pig with elements of that "Pearls before Swine" quote from the Christian Bible that I was named after. It wears a lot of pearls on itself, and it's a good dancer. The abilities it has imply that it's a foodie species that goes at its own whims and tries to set its own pace for life.
It helps that they were from Gen 1 when I started playing. Psychic & Ghost have always been two of my favorite types, & I can even remember the show episodes with Sabrina & the Abra evolutions. I may need a little longer to think about why these 2-3 really stand out to me more than the others.
