The package arrives ridiculously late - around ten at night, with no obvious delivery person. It's just suddenly there at the desk of the Stark building. It contains a toy robot that, once opened, plays this song. Incessantly. Without stopping. It's ~magic~ and there's no battery to remove, but it is possible to muffle the music by stuffing it in a drawer. The spell wears off after a few hours, and at that point it's just a robot toy.
