Mailbox Percussion

Slipping under our door, I dashed down the echoing stairwell straight into the front lobby! Look at that giant wall of shiny metal mailboxes! Dozens of tiny swinging flap doors stretching in neat silver rows! I threw both arms wide, hooked my yellow paws over the ledge, and hoisted myself right onto the mail shelf! Flick! My yellow finger shoved the first brass mail slot flap wide—SNAP-CLACK! The spring slammed it shut with a sharp, ringing crack! Did you hear that percussion?! I dragged both yellow paws right across the whole bottom row—rat-tat-tat-tat-tat! The hollow metal boxes buzzed like an entire tin drum chorus bouncing off the lobby floor!
