Human

Humans AKA Homo sapiens (Latin: "wise man" or "knowing man") are the dominant sentient species on the planet Earth.

Background
Humans are a fairly technologically advanced species occupying Earth. During the 13th birthday of the human girl, Anne Boonchuy, she, along with her 'friends', Sasha Waybright and Marcy Wu were teleported through the Calamity Box that Marcy found, to the world of Amphibia.

Being new to Wartwood, the amphibians at first feared Anne due to her being a strange and intelligent mammal species that they had never encountered before. Grime was also highly suspicious of Sasha initially due to similar reasons and questioned her background. However, the rest of the Valley has not yet been explored in the series and it is likely that there are amphibians who have encountered or have knowledge of humans. One such being Valeriana who owned a stall in the Bizarre Bazaar selling artifacts and relics she had acquired from her years of travel throughout Amphibia. When Anne asked Valeriana if she had seen anything like her, she replied "Not exactly" which indicates that she might have known a human but of different features, like race, skin color, height, hair color, etc.
