Sweet Tooth season 3 brings back the Netflix series to end Gus’ story in the way it should with necessary love and care. Based on the DC (Vertigo) comic book of the same name, Sweet Tooth tells the story of a world where humans have been almost completely eradicated by a disease called the Sick. In their place are the hybrids, a growing population that consists of young children who are half-human and half-animal. The series focuses on Gus, who is seemingly the first hybrid, a deer boy with the biggest heart of all.
