PMD2 (Pokémon Mystery Dungeon: Explorers of Time/Darkness/Sky) isn't a person... It's a set of games. The Chatot from there is notorious for just... Being bad... Actually... Bad isn't even the right word... If you've played these games, you'd KNOW what I mean... *Shudder*
Top left is Loudred, top right is Meloetta, center left is Chatot, center right is Primarina (the one you're talking about), bottom left is Skeledirge, and bottom right is Jigglypuff.
