Angry Birds Samurai

Angry Birds Samurai is a cancelled Angry Birds animated series. All that's known so far is that the series would have took place in feudal Japan with the birds and pigs being redesigned (similar to that of The Angry Birds Movie) to fit the country's premise.

Description

Trivia (Speculation)

 * Concept art of the series was found on Twitter VIA a user called "Angry Birds Facts". In the tweet, he unveiled concept art of the character designs that were supposed to be used in the show.
 * The show could have been made before 2015, as the concept art we got uses the 2010-2014 Angry Birds logo.
 * The character designs resemble that of Agri Birds, and The Angry Birds Movie.
 * In one piece of concept art, there is a pink pig, as opposed to the usual green. It is unknown if this pig was an ally or an enemy of the birds.
 * Terence, Hal, and Bubbles are the only three characters who do not appear in concept art, and since the series was never made, it is unknown if they would've made an appearance in the show or not.
 * The series could've been a promotion for Angry Birds Fuji TV, as both take place in Japan.
 * The show could've been aired on Cartoon Network in North America, as some anime, such as the Pokemon anime, have aired on that channel in English.
 * Since the show was likely a promotion for Angry Birds Fuji TV, the series could've been aired on the Fuji TV channel in Japan.
 * King Pig still uses his design from Angry Birds Toons if the head portion was the only part of him shown. The only main difference is that he doesn't have his crown.
