The mimic makes a bite attack and a pseudopod attack.

Pseudopod

Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 6 (1d4 + 4) bludgeoning damage and the target is subjected to the mimics Sticky trait.

Bite

Melee Weapon Attack: +6 to hit, reach 5 ft., one creature stuck to the mimic. Hit: 9 (2d4 + 4) piercing damage and the target is restrained until it is no longer stuck to the mimic. While a creature is restrained by the mimic the mimic can't bite a different creature.

Swallow

The mimic makes a bite attack against a Medium or smaller creature restrained by it. If the attack hits and the mimic has not swallowed another creature the target is swallowed and no longer stuck to the mimic. A swallowed creature has total cover from attacks from outside the mimic is blinded and restrained and takes 5 (2d4) acid damage at the start of each of the mimics turns.

If a swallowed creature deals 10 or more damage to the mimic in a single turn, or if the mimic dies, the target falls prone in an unoccupied space of its choice within 5 feet of the mimic and is no longer swallowed
