Conifer Rat

Information
The Conifer Rat comes in a set of three, each a tiny rat. While they don't look like much, when left alone they curl up into a ball resembling a pine cone.

Fortunately for you, they're very light sleepers, and are known to make a sound when woken up by people (or things) moving near them.

"They can curl up into what resembles a pine cone! The rarely-observed conifer rat is usually found in forests where it can feed on pine needles and hide from predators by rolling itself up to look like a pine cone. They are shy and prefer to ride in their owner's pockets or pouches. They are often trained for reconnaissance and infiltration due to their cleverness and natural camouflage."
