The goo can move through a space as narrow as 1 inch wide without squeezing.
The goo has advantage on attack rolls against fey and any creature with the Fey Ancestry trait.
The goo can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
The Yaga goo makes two pseudopod attacks. When its Foul Transit is available, it can use Foul Transit in place of one pseudopod attack.
Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 11 (2d6 + 4) bludgeoning damage plus 3 (1d6) necrotic damage.
The goo teleports to an unoccupied space it can see within 50 feet, leaving behind a wretched puddle in the space it previously occupied. A creature within 5 feet of the space the goo left must succeed on a DC 16 Constitution saving throw or take 10 (3d6) necrotic damage and become poisoned until the end of its next turn. The first time a creature enters the puddle's space or if a creature starts its turn in the puddle's space it takes 10 (3d6) necrotic damage and is poisoned. The puddle lasts for 1 minute or until the goo that created it is killed.
