This Buttercup vinyl figure is released by Funko in their POP! Movies x The Princess Bride vinyl figure series.

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! Movies x The Princess Bride series features characters from the romantic comedy fantasy adventure film that tells the story of a farmhand named Westley, accompanied by befriended companions along the way, who must rescue his true love Princess Buttercup from the odious Prince Humperdinck. The film effectively preserves the novel's narrative style by presenting the story as a book being read by a grandfather to his sick grandson.
