Magic Resistance. The Anthony has advantage on saving throws on saving throws against spells and other magical effects

Light Sensitivity. The Anthony has disadvantage on attack rolls and perception checks when exposed to bright light within 5 feet of it. 

Multiattack. The Anthony makes two attacks, one with its bite and one with its slam.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 20 (3d10 + 4) piercing damage. If the target is a creature, it is grappled (Escape DC 15). Until this grappled ends, the target is restrained, and the Anthony cannot bite another target. 

Slam. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit:  18 (4d6 + 4) Piercing damage.

Acid Spit (recharge 5-6). The Anthony regurgitates a blob of acid that bursts at a point it can see up to 60 feet of it. all creatures in a 20-ft-radius sphere centered on that point must make a DC 15 Dexterity saving throw. a creature takes 22 (5d8) Acid on a failed save, or half as much damage on a successful one.

Swallow. The Anthony makes a bite attack against a medium or smaller creature it is grappling. If the attack hits that creature takes the bites damage and is swallowed, and the grapple ends. While swallowed, the creature is Blinded and Restrained, it has total cover against attacks and other Effects outside the entity, and it takes 21 (6d6) acid damage at the start of each of the enttys turns.
If the entity takes 30 damage or more on a single turn from a creature inside it, the Anthony must succeed on a DC 15 Constitution saving throw at the end of that turn or regurgitate all swallowed creatures, which fall prone in a space within 10 feet of the Anthony. If the Anthony dies, a swallowed creature is no longer Restrained by it and can Escape from the corpse using 15 feet of Movement, exiting prone.
