Amphibia (location)

Amphibia is the titular location of the series with the same name. The continent/island itself is a mostly rural marshland that is shaped like a lily pad leaf based on the aquatic plant usually associated with frogs.

Since the events of "True Colors" which King Andrias having the Calamity Box returned into his hands, he used the box's technology to reactivate the factories around Amphibia to build up his personal Frobot military force and quickly industrialize around Newtopia with its outer areas in weeks to the point of stripping off natural surroundings with making lots of pollution as seen in "Olivia & Yunan"

Geography
Amphibia is a magical world inhabited by every species of sentient amphibian—frogs, toads, salamanders, and newts—which live in Amphibia along with various local wildlife creatures and monsters including giant mantises and predatory Herons. Other than marshlands, swamps, forests and jungles, there are deserts, arctics, snowy peaks and so on.

Unlike the wildlife found on Earth, Amphibia's nature is much larger in size which possibly leads to the conclusion that the concentration of oxygen in the atmosphere of Amphibia is higher than that of Earth which enable it to host larger in size varieties of creatures from Earth. Many of Amphibia's fauna (animals) are usually predators of the citizens of Amphibia such as praying mantises and giant weasels, this applies to some flora (plants) as well such as the Carnivorous Tomato Plant. However, there are some animals that can be tamed and domesticated for transportation, farming and pets, such as snails, ladybugs, spiders, birds, etc.

It is currently unknown what lies beyond the surrounding oceans of Amphibia.

History
The mystical and dangerous Amphibia was ruled by the ancestors of King Andrias. Newtopia, the kingdom's capital, was extremely more advanced more than 1000 years ago with loads of advanced technology such as Frobots as the Calamity Box was the source of energy powering the castle and the whole continent. Yet the box was eventually lost under the king's watch by his former female red frog friend which led to Newtopia as a whole losing most of its powerful technological advances, even those that were far from the city on the continent.

Over a millennium later, three human teen girls Anne, Marcy, and Sasha ended up in Amphibia after opening the Calamity Box that Anne had stolen from a thrift store located at Los Angeles, California on her 13th birthday.

Society and culture
According to "Hop-Popular", there are 22,651 amphibians living in the Valley where Wartwood and the Toad Tower are located. The population of the whole of Amphibia has not yet been revealed in the series.

Amphibia as a whole is governed by three sentient Amphibian species: frogs, toads, and newts. These Amphibians are spread all about Amphibia, and are majorly defined by their class structure and societal characteristics. Which the newts are the ones controlling the whole land while the toads are under the newts command to enforce law and order to the other amphibians, mostly frogs.

Places of interest

 * Frog Valley, also called "The Valley": One of the main regions in Amphibia with a population of 22,651, consists of towns and villages surrounded by dangerous mountain ranges and cliffs which occasionally freeze during their yearly cycle in which travel in and out of the valley is impossible. Wartwood Swamp and Toad Tower are both located in the valley.
 * Wartwood Swamp: One of the main towns located in the Valley, Wartwood Swamp is populated by anthropomorphic frogs. Unlike many cities located on Earth, Wartwood is not technologically advanced and uses traditional methods such as bio-luminescent mushrooms for light, bearing the resemblance of a medieval period as swords and bows are still widely used.
 * Plantar Farm: The Plantar Residence is where Sprig, Polly, and Hop Pop live. It is also where Anne currently resides, in the house's basement. In the episode "Family Shrub", it is revealed that the ancestors of the Plantar family also occupied the residence, having made secret chambers for their own studies and occupations.
 * Toad Tower: Also known as South Tower located far from Wartwood, located in an area surrounded by steep cliffs and mountainous terrain. Toad Tower is inhabited by Toad Army soldier toads with Captain Grime as their leader of this garrison. Sasha, one of Anne's human friends, was formerly held prisoner here before joining the army as a second-in-command. The garrison under Captain Grime's rule are known as the protectors (actually bullies that were commanded by the Newtopian military) of the Valley.
 * Ribbitvale: It's the most expensive town in all of Amphibia, where the mansion Ribbiton Manor owned by Wigbert Ribbiton and his son's real home is located.
 * Newtopia: A major city and known throughout Amphibia as its capital. Newtopia is the residence of the ruling monarch King Andrias.
 * Bittyburg: A small town located in the desert region of Amphibia. This town, as suggested by its name, is home to a small population of miniature frogs, no larger than a cell phone.
 * Stony Gulch: A relatively mid-sized town made up of primarily stone structures and buildings. This town is home to the Curiosity Hut, a small oddities museum based off of the Mystery Shack from Gravity Falls.
 * The Dry Swamp: A sandy, desert-like area with little to no vegetation or water. Primarily consists of sand dunes with little to no amphibian inhabitance.
 * Baby Town: A town located east of Stonewell in the Dry Swamp. It is implied that the town is home to numerous amounts of Amphibian babies.
 * Stonewell: A small desert town located in the Dry Swamp, north of Mount Ridgemore and west of Baby Town.
 * Mountain Ridgemore: A large mountain in the Dry Swamp between Banksville and Stonewell.
 * Banksville: A town located in the Dry Swamp with the slogan "We have money!" Very inviting to bank robbers.

Trivia

 * The land of Amphibia resembles that of a giant lily pad, a plant often associated with frogs, toads, salamanders, newts and other swamp animals/creatures, such as dragonflies.
 * Amphibia is named after the biological classification of amphibians, which makes sense since the majority of the population inhabiting Amphibia are amphibians themselves.
 * It is possible that the world of Amphibia has more oxygen in its atmosphere than that of the environment of Earth, as enriched oxygen allows organisms to reach significant heights. This may be why its creatures grow many times larger than their Earth counterparts.
 * During some nights, the occurs when the moon moves into Amphibia's world. The moon's shadow creates the blood moon effect, which would make the area in Amphibia like Frog Valley have a bright red surrounding. Moreover, the lunar eclipse is seen in the Amphibia show posters and the season 2 version of Anne's Theme.
 * The native currency used in that world is Copper.
 * The map of Amphibia opened by Hop Pop shows the directions of north, east, south and west, as it seems facing Amphibia's lily pad leaf opening is west.
 * In "Kermit Reacts to Amphibia", Kermit the Frog compared the island's appearance to that of the swamp he grew up in, which was "wetter, muddier, and closer to the Interstate."
 * On Reddit, Matt Braly stated that Amphibia is as old as planet Earth, and is as big as the staff need it to be, which he guessed was -sized.
 * In Reddit, Matt suggested that time may flow differently between Earth and Amphibia, but whether this is true is still unknown.
 * Time passage appears to be consistent between Amphibia and Earth. At the 2021 SDCC, Matt confirmed time moves normally between the worlds, so the girls have been gone from LA on Earth for 5 months. This was confirmed in the episode "The New Normal".
 * In a previous Twitch stream, Matt said there was no reason that the "Boiling Isles" from The Owl House would not be connected to Amphibia.
