2.
Generally known as one of the new Pokémon released with the 5th generation Pokémon games. It is the exact opposite of manliness, being pink, fat, and has flowers printed on its skin.
People love to hate Munna. It is both respected and feared, but mentioning or seeing the image of Munna usually invokes disgust.
OH GOD! NOT MUNNA!
