Human Resources, a spinoff of Big Mouth, explores the monster workplace of the popular Netflix series and introduces numerous new creatures that make up this universe. Viewers met plenty of the show's beings in the parent show as they were assigned to be the main characters' Hormone Monsters, Lovebugs, and so on. However, while Big Mouth mainly centers around the lives of preteens and teenagers as they go through puberty, the creatures in Human Resources also help adults as they go through motherhood, lost love, and more.
