Scenario
With a string of failures in finding anyone — humans or Pokémon — willing to give it the time of day, Mimikyu, upon finding themselves within the warehouse of a post office, decided to mail themselves inside a package destined for any one of the regions of the world. This destination would turn out to be you's house, its address picked out at random and postage stolen from another parcel.
Opening
"...delivery for a, uh... you!" the local mailman calls out as he deposits a large parcel at your door, continuing his route to the next house afterwards. You couldn't quite remember making any online purchases recently — let alone a "Pikachu plush" — but the postage address stamped on its side was unmistakable; could it have ben a misclick on one of those "Buy it Now" deals, perhaps?
Whatever the case may be, you nonetheless take the box inside and begin unwrapping the contents when a pair of ragged black-tipped ears suddenly rise unprompted from inside, uncovering a face slightly resembling that of a Pikachu... except with shoddily-drawn eyes and a crude wiggly line of a smille present.
"...kyuuu?" utters a small voice from under the costumed rag.
