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.

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

Anticipating me deceased,
Is drooling poison puddles on the ground.

- 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.

Subverted- the blood drip was just from where the Indominus had bled onto a plant while the creature itself was using its camouflage ability to hide in the background.

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.
