Energy Resistance (Su): the creature only takes 50% damage from cold, electricity, fire, & water (force) energy types
Mimic Shape (Ex): a Mimic can assume the general shape of any object that fills roughly 1,000 cubic feet (10Χ10Χ10), such as a massive boulder, a wagon, or a vault; the creature can substantially alter its size by expanding or contracting its internal mass (this does not alter its statistics), allowing it to appear as small as a Medium-sized object (examples: chest, bed, corpse) or as large as a Huge-sized object (examples: house, tree, pond); anyone who examines the Mimic closely (within 5) can detect the ruse with a successful Spot check opposed by the Mimics Disguise check + 10 (of course, by this time it is generally far too late); changing to a different shape is a free action, & so it does not provoke attacks of opportunity
