Shapechanger. The mimic can use its action to polymorph into a fruit 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 fruit.

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

Slip Through Fingers. When the mimic is grappled by another creature, its speed is not reduced and it can still benefit from any bonus to its speed.

Pseudopod. Melee Weapon Attack: +3 to hit, reach 1 ft., one creature that is holding the mimic. Hit: 3 (1d4 + 1) bludgeoning damage, and the mimic enters the target's mouth.  The target is subjected to its Adhesive trait and is grappled by the mimic.  While grappled in this way, the target's mouth is glued shut.

On its turn, if the target succeeds on an escape roll, it can make a DC 11 Strength (Athletics) check to pull the mimic out of its mouth and either fling it up to 20 feet or crush the mimic in its grip (an unarmed attack against the mimic) as a bonus action.

Bite. Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 3 (1d4 + 1) piercing damage plus 2 (1d4) acid damage.  It the mimic is in a creature's mouth, it severs and consumes the creature's tongue.
