Shapechanger. The mimic can use its action to polymorph into a ham, turkey, side of beef, or other large meat item 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 (Object Form Only). The mimic adheres to anything that touches it. A Large or smaller creature adhered to the mimic is also grappled by it (escape DC 12). Ability checks made to escape this grapple have disadvantage.

False Appearance (Object Form Only). While the mimic remains motionless, it is indistinguishable from a fine meat item.

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

Greasy. The ground in a 5-foot radius around the mimic is covered in slick grease which is difficult terrain.  Each creature that enters the area or starts its turn in that area must succeed on a DC 12 Dexterity saving throw or fall prone.

Pseudopod. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) bludgeoning damage. If the mimic is in object form, the target is subjected to its Adhesive trait.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 2) piercing damage plus 3 (1d6) acid damage.
