The Bright Red Peril

A gleaming crimson flag stuck out like a sassy salute atop a metal post! Sufferin' succotash, I trotted down the crunching gravel driveway, convinced a challenge was being issued. I bounded onto a flat boundary rock and lunged upward to grasp the bright red metal marker. *Clang-snap!* The joint gave way with a dramatic groan, swinging downward and flipping open the heavy curved lid of the metal mailbox! The sudden iron echo rattled straight through my paws. Peering inside the dark, hollow tunnel, I saw only a single fallen dry leaf resting in the gloom, completely unbothered by my daring ambush.
