Actions

Multiattack. The wormling makes two attacks: one with its bite and one with its stinger.   Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 ( 1d8+3 ) piercing damage, and if the target is a Small or smaller creature, it must succeed on a DC 13 Dexterity saving throw or be swallowed by the wormling. A swallowed creature is blind and restrained, it has total cover against attacks and other effects outside the wormling, and it takes 3 ([1d6]) acid damage at the start of each of the wormling's turns. If the wormling takes 10 damage or more on a single turn from a creature inside it, the wormling must succeed on a DC 21 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 wormling. If the wormling dies, a swallowed creature is no longer restrained by it and can escape from the corpse by using 5 feet of movement, exiting prone.   Tail Stinger: Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 5 ( 1d4+3 ) piercing damage, and the target must make a DC Constitution saving throw, take 10 ( 3d6 ) poison damage on a failed save, or half as much damage on a successful one.
