Frog Frog is a creature that lives in two worlds: water and land. This crab of the woods is revered for its adaptability, knowledge and power to traverse worlds and inhabit diverse realms, both natural and supernatural. Frogs are primary spirit helpers of shamans. In the art this great communicator is often shown sharing its tongue or touching tongues with another creature in an exchange of knowledge or power. Frog is identified by a large mouth, usually thick-lipped and has bent legs with webbed feet and a protruding tongue.
