Hibernate

A creature sent into hibernation by a druid sleeps in a torpid state for as many weeks as the caster desires (up to one week per caster). A successful saving throw vs. spell negates the spell. If affected, the creature's need for oxygen, food, water, and such are all but negligible for the duration. The creature can be awakened, but will go back to sleep when it is no longer interrupted unless it makes another saving throw vs. spell. When the spell expires, the creature will awaken with a very intense hunger.

The caster can affect 1 large creature the size of a bear, 2 man-sized creatures, or 3 smaller creatures. Humans and humanoids are as vulnerable to the spell's effects as any other creature. Sentient or quasi-sentient plants and plant beings will go dormant if subjected to a hibernate spell, just as they would in winter.

The material component is some fur from a mammal that hibernates.
