For this spell, you need

  • Christmas
  • Snow
  • Five moonstones

So, go out on a midnight Christmas and draw a pentagram in the snow. Place on each point of the pentagram a moonstone.

Now chant the following three times:

Creatures of day and night, 

grant me your power and your form. 

Grant me your senses, lend me your ears. 

Be kind to me. Release me from my human form.

So mote it be!

Optionally you can sacrifice your blood to boost the spell.

Then visualize the animal that you want to shapeshift into.
