Gremlins

Overview
Gremlins are small, frog-like creatures that primarily assist in the science of Alchemy. They are able to use their bodies like a small brewery to create potions within themselves when given the correct ingredients.

Physiology
Gremlins can grow up to around 6-12 inches and can weigh up to 12-16 ounces. They have a distinct Frog-like body, and have feet and sticky pads similar to them as well. Their skin is mostly a dark green, with yellow-green or lime green spots dotted round its body. The top of it's body is mostly opaque, prominently on the head and down the spine to the base of the tail bone. From there, it's skin becomes more and more clear until the underbelly which is completely translucent.

The head's shape is unsurprisingly similar to a frog's, but with some distinct differences. The ears of a Gremlin are bat wing shaped, which can be moved by the Gremlin freely. They also have pig-like snouts, with which they use to sniff out academical ingredients. Their mouths are like that of a leech's, circular and with many small, razor sharp teeth circling inside it.

What makes Gremlins so important to alchemists is their very intriguing digestive system. Gremlins have two stomachs: A personal stomach for regular feeding and hydrating, and a social stomach, not too different from an Ant's. What alchemists focus on is the Social stomach, because of it's special properties. The social stomach has a particularity thick mucus layer that makes it impervious to toxic and particularly acidic components. Along with the mucus, gremlins also excrete a natural preservative to keep the contents fresh within it. This enzyme is known to alchemists as Alcahest, the catalyst for almost all alchemical creations.

History
The Gremlin itself is not native to the Adventurer's dimension. They come from an otherworldly plane that is still mostly unexplored. But what is known is that most of their world consists of mountainous swamps and craggy marshes with year round hot, humid weather.

The first Gremlins appeared when interdenominational rifts opened during the Rift War. And since then, many astute scientists have ventured into Rift Storms to collect these creatures to assist in many different fields of science and alchemy, although many people debate whether it is ethically sound.

Trivia

 * Despite being so small, Gremlins are actually quite intelligent. They express emotion, have their own language, and in some cases able to speak and read other languages. This, although, is quite rare.
 * Although both male and female gremlins produce Alchahest, it is noted that female gremlins produce more than males
 * A common nick-name for Gremlins are Brewer's Imps, due to them being famous for assisting in the creation of potions in alchemy
 * Gremlins are notoriously indestructible. They can be squashed, stretched, bounced and fit into extremely tight places. It would take piercing them with an extremely sharp object or explosives to due them in.
