Shapechanger. The mimic can use its action to polymorph into a pie or back into its true, amorphous form. Its statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.

Adhesive. The mimic adheres to anything that touches it. A Medium or smaller creature adhered to the mimic is also grappled by it (escape DC 11). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from an ordinary, inanimate pie.

Grappler. The mimic has advantage on attack rolls against any creature grappled by it.

Pseudopod. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage plus 2 (1d4) acid damage.

Pie in the Face. The mimic flings itself up to 10 feet through the air towards a creature it can see.  That creature must make a DC 12 Dexterity saving throw.  On a failed save, the target takes 3 (1d4 + 1) bludgeoning damage and is grappled by the mimic.  Until this grapple ends, the target is blinded.  On a successful save, the mimic falls harmlessly to ground at the target's feet without the target being subjected to any of these effects.

Smell of Pie (3/Day). The mimic releases a strong musk that targets all humanoids within 30 feet of it. Each target must succeed on a DC 11 Wisdom saving throw or be charmed by the mimic for 1 minute. A creature charmed in this way does nothing on its turn except move as close as it can to the mimic. A creature charmed by the mimic can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
