What is the first hint that a giant monster, yet unseen, is towering over some characters, or clinging to the ceiling above them?
Not the vibration of its moves, the sound of its breathing, the putrid smell or anything like that...
No, in some case, the very first hint they'll ever get of this menacing presence is... some liquid splashing over their heads or shoulders.
Most often drool, though it can be other secretions. Sometimes this drool is acidic, and they're really in trouble. May be also the blood or remains of the monster's last victim for extra fun.
- The disgusting Licking Woman from Junji Ito's Black Paradox series.
- In Delicious in Dungeon, Marcille the elf receives some slime on her head falling from the ceiling, but the early warning isn't enough for her to avoid a Blob Monster on the face.

- Moribito: Guardian of the Spirit: Torogai runs into a cave in Nayug, seeking an escape route. Something splashes onto the floor beside her, and she realizes she's run into a trap. She gets out anyway... through the worm creature's digestive tract. Ick.

- "A Nauseous Nocturne", from The Essential Calvin and Hobbes:

Comes a noise much like a faucet
Makes: a madd'ning drip-drip-dripping sound.
It seems some ill-proportioned beast,
Anticipating me deceased,
Is drooling poison puddles on the ground.
- In Alpha and Omega, the bear slobber on Humphrey after he accidentally hurts the bear's child.

- Hotel Transylvania: A harmless (and very cute) version of this happen during the prologue — while Dracula is overseeing the plans for the movie's titular hotel, a blob of saliva splatters onto the blueprints.

- In The Girl of the Golden West (a play before it was an opera), Minnie is trying to hide the wounded Johnson in a loft from Jack Rance, who is also the sheriff and comes looking for him after having shot at him. She is just saying goodnight to Rance, and he holds out his hand to her, when a drop of blood falls on it from the boards above. Minnie says that she must have scratched him, but then another drop of blood falls from the loft on his hand, betraying Johnson's hiding place.
