Shapechanger. The mimic can use its action to polymorph into a cat or back into its true, amorphous form. Its stats are the same in each form and any equipment it is wearing or carrying isn't transformed. The mimic reverts to its true form if it dies.
Grappler. The mimic has advantage on attack rolls against any creature grappled by it.
Adhesive (Cat Form Only). The mimic adheres to anything that touches it unless it wishes not to do so. A huge or smaller creature adhered to the mimic is also grapped by it (escape DC 13). Ability checks made to escape this grapple have disadvantage.
False Appearance (Cat Form Only). Whilst the mimic remains motionless, it is indistinguishable from an ordinary cat.
Multiattack. The mimic can make three attacks, two with its pseudopods and one with its bite.
Pseudopod. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) bludgeoning damage. If the mimic is in its cat form, the target is subjected to its Adhesive trait.
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) piercing damage plus 4 (1d8) acid damage.
