Genshin Impact

Mud Frog

A small frog that often appears in wetlands.
This animal is very common in wetland areas, and its body secretes a mysterious sticky substance that has much medicinal utility. As opposed to normal frogs, the yellow Mud Frogs are better at camouflaging themselves along wet banks.
They say that in Fontaine, people refer to brigands who escape capture often or evildoers who evade judgment as "mud frogs in butter."
