Tide Corrupted Seagull
Individually, they're stupid, but combined there is a malevolent intelligence looking through them.
Not even the gulls are safe. Or sane.
Description
About halfway across the rocky rise, you spot dozens of oversized, haggard seagulls nesting among the stones. Their feathers are patchy and dull, their bodies slick with tide-corrupted slime. The nests are littered with mottled eggs, shredded fish, and... something more human.
These gulls do not scatter when approached.
They watch—with too many eyes, too long.
