Justin Felbinger

On her 13th birthday, Anne is peer-pressured into stealing a mysterious music box known as the Calamity Box that magically transports her and her two best friends Sasha Waybright (Anna Akana) and Marcy Wu (Haley Tju) to the world of Amphibia, a wild marshland tropical island inhabited by anthropomorphic amphibians and threatening creatures, where they are separated from each other.

Anne is taken in by the Plantars, a family of frogs consisting of excitable young Sprig (Justin Felbinger); unpredictable and adventurous baby pollywog Polly (Amanda Leighton); and overprotective and traditional grandfather Hop Pop (Bill Farmer) who live on a farm in the town of Wartwood.

As she bonds with her newfound family, Anne gradually learns what it means to be a hero and develop a true friendship, while trying to find her friends and return home.

Sasha allies with Captain Grime (Troy Baker), leader of the warfaring toads of Toad Tower, who seek to control their home of Frog Valley.

Marcy ends up in Newtopia, the capital of Amphibia, the seat of the government and home to Lady Olivia and General Yunan, the Princess and general of Amphibia.

In the second season, Anne and the Plantars go on a road trip to Newtopia to learn the secrets of the Calamity Box and find a way to get Anne home.

There, Anne reunites with Marcy, who offers to help restore the box's power through a series of ancient trials, unaware that Amphibia's ruler, King Andrias (Keith David), secretly has plans for them.

Meanwhile, Sasha and Grime plot to invade Newtopia and overthrow the monarch, allowing the toads to rule over Amphibia.

In the third and final season, Anne and the Plantars are transported to Anne's home in the suburbs of East Los Angeles, where she must now help them adjust to the human world and keep their identities a secret while searching for a way to return to Amphibia and stop Andrias's invasion of the multiverse.

Upon returning, they discover Sasha and Grime have formed a resistance force in Wartwood and aid them in their rebellion against Andrias, who is using Marcy as a host for his master, an multi-eyed entity known as the Core.

Matt had been developing the series with prototype designs of the protagonists in early 2015.

On February 19, 2018, Amphibia was greenlit by Disney Channel alongside The Owl House with an order of 20 episodes.

The series was created and executive-produced by Matt Braly, previously a storyboard artist on Gravity Falls and later a director on both Gravity Falls and Big City Greens.

According to his Twitter account, he had been working on the series for almost two years before being greenlit, though he began to conceive the project while work on Gravity Falls began to conclude.

Amphibia is an American animated television series created by Matt Braly that aired on Disney Channel from June 17, 2019 to May 14, 2022.

The series features the voices of Brenda Song, Justin Felbinger, Bill Farmer, Amanda Leighton, Anna Akana, Troy Baker, Haley Tju, and Keith David.

Amphibia has received positive reception, with praise for its characters, animation, voice acting, humor and emotional weight.

The series chronicles the adventures of Anne Boonchuy, an independent, fearless and brave Thai-American girl (Brenda Song).

On May 15, 2019, Disney Channel renewed Amphibia for a second season of 20 episodes ahead of its premiere.

On June 23, 2020, the show was renewed for a third season of 18 episodes ahead of its second-season premiere.

In a Reddit AMA, Braly referred to Amphibia as a "three act story" with season two as the "2nd act".

He further clarified in the AMA that he had "structured the story for 3 [seasons] currently", implying that the third season would serve as the final season of the show.

Later on March 16, 2022, storyboard artist Alex Swanson confirmed on Twitter that season 3 was set to be the show's last.

The show was based on Braly's childhood trips to Bangkok, Thailand.

The series' tone was inspired by films by Aardman Animations and Studio Ghibli, while its storytelling format was inspired by Gravity Falls (which Braly previously worked on) and Steven Universe.

Braly was also inspired by video games such as The Legend of Zelda and Chrono Trigger when creating the series.

Other inspirations for the series include shows Braly watched in his childhood, such as Batman: The Animated Series and Disney's Gargoyles; he precisely cited Gargoyles as an inspiration for the series' story arc. According to Braly, one of the reasons he created the series was because he wanted a show whose lead character had a similar arc to Gravity Falls character Pacifica Northwest, as he felt that "to have this character change so drastically was so rewarding, and that's why [he] knew [he] wanted [his] own show to have some of that element as well".

The character of Sprig went through several changes through development, with the developers constantly giving him different ages, before choosing to make the character a younger brother-like figure for Anne.

Similarly, Anne, Sasha, and Marcy were originally fifteen-years-old because they wanted the series to have a high school-like feel, but were aged down in order to appeal to the series' target demographic; due to this, the trio often realizes actions more akin to high school students, such as driving and having part-time jobs.

The series marks the first animated show to have a Thai-American lead.

Braly, who is also Thai-American, chose to make the series lead character, Anne Boonchuy, Thai-American because he wanted more Thai characters in television series.

According to Braly, Anne was loosely inspired by his grandmother.

He described Anne being Thai-American as "a number one priority", as he wanted Thai-American kids to see themselves reflected on television.

Braly also made the character dark-skinned due to his mother's family being tanned.

Season 3, which is set on Earth, further delves into Anne's Thai heritage, including an episode set at a Wat Thai temple in Los Angeles.

Braly described the temple's representation in the episode as "pretty accurate", as it is important for him to represent Thai culture accurately.

Braly chose to make the series to be centered around a frog-populated world because he felt that, due to how frogs change from tadpoles to frogs, they were perfect for the series' theme of change.

Braly also implemented themes involving social classes and environmental awareness into the series, with Anne interacting with frogs of several different social backgrounds and learning to "appreciate the natural world around her".

Three of the series' four writers are women, which Braly felt necessary due to the show centering on a teenage girl.

Storyboard artists are allowed to pitch their own ideas for an episode, a practice Braly took from his time at Gravity Falls.
