Beaver fetishes represent home, family and unity. They are revered for  their building skills and associated with water by some north eastern  tribes. In Zuni they are carved by a variety of artisans some of whom  put little tiny twigs in their mouths. 

 Beaver’s medicine brings you the wisdom of creativity, maintaining the  ability to be productive in all ways by not limiting your options, being  persistent, using available resources, finding and using alternate ways  of doing tasks, master builder of all things, not damming the flow of  experiences in life, achievement through completion of tasks,  understanding the dynamics of group work, protecting, cooperation,  fertility and new promise. 

Power of the Fetishes: The Zuni people feel  that the power of the Zuni  fetish lies within the heart of the Zuni Fetish, much like the power of  the animal the fetish represents.  It is believed that the hearts of the  great animals of prey are infused with a spirit or medicine of magic  influence over the hearts of the animals they prey upon.  The "breath of  life" derived from their hearts whether near or far never fails to  overcome a game animal.  The breath of the powerful prey animal  overcomes the weaker animal, piercing it's heart and causing it's limbs  to stiffen and the animal itself will lose it's strength.  The roar or  cry of the beast of prey is fatal to the game animals which hear the  cry.  It charms their senses as does the breath of their hearts.  Since  the mountain lion lives by the blood or "life fluid" and flesh of the  game animals, and by these alone, he is endowed not only with the above  powers, but also with peculiar powers in the sense of sight and smell.   Moreover, these powers as derived from his heart, are preserved in his  fetish, since his heart still lives, even though his person has been  changed to stone.
