looking around the the box Mary found another slide-out drawer and a note that was resting atop the vials here. The note reads:
These are the Inanimate vials, use extreme caution when using the vials here for obvious reasons, as a precaution it is recommended you use the timer and/or animated vials in this section. Timer vials, regardless of how much you drink, will make the effects of the vary next vial you take last only the period of time that is marked on the side of the vial. Animated vials, if any amount is taken with or before another vial, will allow you to have full control of any form you take.
Mary now knowing that she can still transform fully back is curious to try one of these vials, but which one does she take?
