As madame Illusia was opening her show as she always does by greeting everyone and making her act know to all the different people attending, she presented her brand new contraption.
This is the hooves box. With this my eager participants you can turn into any hooved animal your heart desires provided you are willing to live life down on all fours and trade your hands for another pair of legs.
As she said this she pointed at a horizontal contraption with a very complicated mechanism of pipes that were connected to a central tank which was filled with chunks of a glistening black substance. There was fairly big pile of wood underneath it that surely was to be ignited. The complicated piping ran from the pot to a secondary black vessel which would redirect the boiling hot liquid once it was poured to each of the four gaps for a participant's legs and hands. They were also fitted with adjustable supports to sustain their legs while they were changing to accommodate a quadrupedal stance.
Who wants to be the first one tonight to receive one of nature's most redundant locomotion systems, the hooves, the animal to which they belong is up to you.
