Usher (Michelle Tea) a doe of a different re mi, and Stew (Ed Wolf) a red stag unicorn deer, are a pair of indispensable workers employed to receive souls and weigh them on a scale. The light-hearted souls return to earth and heavy-hearted souls are fed to a monster. The Fungal Kingdom stands to inherit the earth due to the dramatic increase in heavy-hearted souls and now fate of the world rests in their hooves.
