The goo can move through a space as narrow as 1 inch wide without squeezing. \n'b'  Deadly to Fey . The goo has advantage on  attack  rolls against fey and any creature with the Fey Ancestry trait. \n'b'  Ooze Nature . The Yaga goo doesn\xe2\x80\x99t require sleep. \n'b'  Spider Climb . The goo can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check. \n'b'\n'b' Actions \n'b'\n'b'  Multiattack . The Yaga goo makes two pseudopod attacks. When its Foul Transit is available, it can use Foul Transit in place of one pseudopod  attack . \n'b'  Pseudopod .  Melee Weapon Attack : +7 to hit, reach 5 ft., one target.  Hit : 11 (2d6 + 4) bludgeoning damage plus 3 (1d6) necrotic damage. \n'b'  Foul Transit (Recharge 4-6) . 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\xe2\x80\x99s space or if a creature starts its turn in the puddle\xe2\x80\x99s 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. \n'b'\n'b' Reactions \n'b'\n'b'  Puddle Splash . When a creature the Yaga goo can see targets it with a  melee attack  while within 5 feet of the goo, the goo can  teleport  to a puddle created by its Foul Transit, if that puddle\xe2\x80\x99s space is unoccupied, negating the damage from the  attack . If it does, the attacker 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. \n'b'\n'b' About \n'b'  Simmered Down . Adventurers who meet Baba Yaga and offend her are usually boiled down and turned into Yaga goo, an oozing, loyal spy. The recipe also exists outside of Baba Yaga\xe2\x80\x99s cauldrons-some hags and ancient witches know how to turn foes into Yaga goo. \n'b'  Scent of Stew . Yaga goo is said to smell rather appetizing, a bit like pork or a hearty mutton stew. This scent is difficult to distinguish from actual stew, so Yaga goo is known to do some of its spying for Baba Yaga in actual kitchens and cauldrons.'
