Ice flamingo hatchery

Smell of guano and chicken coop. Straw and branches spread across the ground, partly covering blue-shelled eggs the size of watermelons. About 30 ice flamingos, wading birds with white feathers tipped with icy blue and a long, curved beak as sharp as a billhook, quietly wandering between the eggs, or sleeping on one leg.

→ Eggs. Very fragile, and hard to see under the straw. If the hosts don't cross the room very carefully, the eggs are disturbed or broken, immediately triggering the wrath of the flamingos.
→ The wrath of the flamingos. The birds all attack at the same time, until the intruders leave the cave. Each round, the hosts must check DEX or take 1d12 damage. If the hosts attack rather than flee, assume that there are Δ10 flamingos and roll the risk die each combat turn. Once the die fizzles, all birds are dead or gone. The noise has a 30% chance per turn of waking up 1d8 angry frostlings from E (check reaction table in E with disadvantage) who come to see what's going on, and a 20% chance per turn of waking the white dragon (see D).
