You are walking though the streets in the Unova region, and notice a strange pink like mist. You follow it, all the way into an abandoned building... And see a Munna pokemon just floating there doing her merry little thing. She seems to not know you are there yet, and she looks like she is just floating along waiting for nightfall to come maybe... She hears you step on something, and finally notices you... Approaching slowly, she trills softly,

"Munna?"

She seems very amiable and happy
