From Lost Fables Wiki
Disgusting, three to four foot tall, slimy green-blue scaled little creatures, Sea Monkeys are known for setting up small fishing villages composed of huts, a foot or two deep in the waters in rivers and off the coasts. They’re very minorly intelligent, just enough to use tools and identify easy targets, but generally not intelligent enough to realize the consequences of their actions, leading them to be a dangerous nuisance anywhere they take root. They’ll attack and eat anything they think they can take down, but are cowards, and will only attack in numbers. They’re very afraid of fire, and can be difficult to eradicate in a place due to their strong swimming, ability to breathe both water and air, and hermaphroditic nature, allowing even a single one which escapes restarting its colony, assuming it can keep itself fed for long enough.
