Hallow

Has a secondary (full moon and Halloween night) form. Name is pronounced Hollow when in secondary form. Normally 3 feet tall at the shoulder, secondary form is about 9 inches at the shoulder. When in their usual form, their personality is of a benevolent being. However, under the effects of a full moon (and on Halloween night, regardless of the moon), they do a 180°, becoming a mean-hearted trickster.
