Walking in the forest, if you have luck, you can find Foreffin's egg under trees' roots. You must be very careful if you want to take it. The eggs have a fluffy texture and deer antlers. The little creature who live in is too vulnerable in the egg stage.
Foreffins are known as tree and forest protectors. Many people say that they live in symbiosis with forest and develop magic connections with their environment. They eat some insects and invasive plants living between roots. In general, they are quiet creatures.
But if you hurt a tree, Foreffins become nervous and fierce. Remember that they have powerful claw and aren't afraid to use it.
