Funko POP! is a crossover vinyl figure series by Funko and other famous franchises such as Disney, Pixar, DC Comics, Marvel Comics, Simpsons, South Park, Uglydoll, etc. Each POP! figure is about ~3" to ~5" tall and crafted in a Japanese anime/manga super-deformed style (NOTE: due to the unique design of each character, the actual size of the figures may be smaller or bigger than stated).

The POP! Animation x BoJack Horseman series features characters from the animated sitcom that takes place in an alternate Hollywood where humans and humanoid-esque animals live side by side where the washed-up star, BoJack Horseman, plans his big return to celebrity relevance with a tell-all autobiography that he dictates to his ghostwriter Diane Nguyen.
