Item: a Klefki, a flying metal fey with a yen for hoarding keys, seeking them out whenever they are available and rarely letting them go; will willingly go along with someone it judges to be a good source of keys. Once it has latched onto the keys, it is fairly willing to be helpful and use them to open or shut locks, although as a Fey it is not great at telling the difference between mortals, and may be perfectly willing to unlock and relock the same keyhole many times in a row if given opposing orders by two different people. As it finds more keys, it grows larger to accommodate them.
