The Silver Trigger

The garden was secured. Time to breach the interior! I slipped beneath the back door flap and hit the cold kitchen tile. Straight ahead stood a towering silver cylinder guarding the corner. At its base—a ribbed metal pedal jutting out like an armed mechanism. A direct challenge! I didn't creep. I sprinted across the slick tile and threw my entire weight into a two-footed stomp right onto the lever. CLANK! The giant lid swung wide open above me with a hollow metallic roar. A blast of air rushed out! I locked my boots, holding the pedal pinned flat. Subjugated.
