Christmas Gift Mimic

Shapeshift. The mimic can shape-shift into any mundane object of its choosing. This can range from an ordinary piece of furniture, a child's play toy, or a useful every-day item. While polymorphed in this way, the mimic cannot be detected. 

Unseen Ambusher. Once per turn, the mimic can choose to go Invisible for 3 turns. While Invisible, the next attack roll it makes is a guaranteed Critical Hit. 

Secret Compartment. The mimic can store an infinite amount of material in its bottomless belly. Any equipment stored in this way cannot be destroyed, unless the mimic dies. 

Sweet Scent. All creatures that start their turn within 10 ft. of the mimic must succeed a DC 30 Wisdom Saving Throw or become Charmed for 2 turns. 

Sugar Surge. If the mimic consumed any amount of sugar, it acquires the effects of haste, blur, enlarge, freedom of movement, and longstrider for 2 turns. 

Adrenaline Rush. Whenever the mimic reduces a creature to 0 HP, it acquires an additional action. There is no limit to how many times this can happen. 

Multiattack. The mimic makes 6 of the following attacks below in any combination it chooses.

Peckish Bite. Melee Weapon Attack: +22 to hit, reach 5 ft., one target. Hit: 63 Piercing damage and the target is Grappled (escape DC 22). While Grappling, the mimic cannot attack another creature. This attack deals double damage to Prone creatures. 

Delicious Chomp. Strength Saving Throw: DC 25, reach 5 ft., one Medium or smaller target. Fail: The target is swallowed. While swallowed, the affected entity is Restrained, Blinded, takes 87 Acid damage per turn, and has total cover against attacks made outside of the mimic. A creature that dies while swallowed will be immediately digested, and cannot be brought to life unless by the Wish or True Resurrections spells. When the mimic dies, all swallowed creatures will be vomited out,  loosing all of these conditions. 

Ribbon Whip. Melee Weapon Attack: +22 to hit, reach 20 ft., one target. Hit: 57 Bludgeoning damage and the target is knocked Prone. 

Strangling Wrapping. Strength Saving Throw: DC 25, one target within 60 ft. Fail: The target is Restrained and takes 40 Bludgeoning damage at the start of their turn. The target can repeat the Saving Throw to remove these conditions. Success: The mimic cannot use this ability on the same target. 

Ornament Bomb. Dexterity Saving Throw: DC 28, one target within 80 ft. Fail: 60 Fire damage and 30 Force damage. Success: Half damage only. Fail or Success: The target receives the Prone and Defeaned conditions.

Explosive Surprise. The mimic places 3 tiny toy bombs within 5 ft. of itself. These bombs each have 20 HP, 11 AC, Immunities to Psychic and Poison damage, 60 ft. of walking speed, and +0 Initiative. On their turn, the toy bombs will sprout small chicken legs and move towards the closest hostile target (any creature that the mimic chooses). The bomb will then explode, and all creatures within 40 ft. must succeed a DC 30 Dexterity Saving Throw or take 60 Fire damage and 60 Force damage. Creatures that succeed this Saving Throw take half damage only.  

Naughty Strike. Trigger: When a creature ends its turn within 5 ft. of the mimic. Response: The mimic makes a Peckish Bite against that creature.
