You considered your odds, and you realized that the squirrel is a good choice, as its already greedy nature could provide you with more nutritions.
You enter the less dense forest and look for a nut tree. After a short while you come upon the spirit of a hazelnut tree and you hide behind its leafs.
After a short while a squirrel spirit apears nearby your hazelnut tree, to gather some nuts. The squirrel is totally unexpecting and you choose just the right moment
to enter the fight. You land on the neck of the squirrel spirit and you also manage to land a direct bite on the squirrel fiend's neck. After a while of choking, biting and beating the
creature below you, you finally manage to "kill" it. As the last breath leaves the squirrel spirit you realize that you are absorbingthe power of the spirit. It isn't much, but you gain just enough to gain a power.
While you are succesful in hunting, you consider many other options to be more effective at gathering essence. You consider pumping essence of yours into others, but the only way to do it you imagine is giving it your "blood". Maybe experiment a little bit?
What will be your Power? Also what will your next course of action be?
