The Amphibiosans are humanoid creatures who are smaller and lankier than the average human. They resemble Terran amphibians, with whom they share several traits.


Even though they have different genders, they don't reproduce like Humans. When they feel a strong love for someone, they go into reproduction stage. If they are touched while in their reproduction stage, they will get pregnant. Their Smizmar is the one who inspires the reproduction stage even if the one who gives their genetic material is not that person. This reproduction stage is usually why many Amphibiosians do not know what sex is and it is also why Kif wears gloves all the time.

Life Cycle

Amphibiosans have a long life cycle. They have a large number of offspring who have to fend for themselves for many years until they grow legs. They have to make it into the lake without being eaten. After this stage, they are humanoid figures, like Kif. Their last stage is a hookworm stage in which they are a swarm of hookworms.
