A Solid Green Box

A massive green steel box blocked my line of sight on the sidewalk. Thick metal, bolted into a raised concrete slab. I marched right up to the seam. A heavy padlock hung from the latch, coated in dark green paint. I lowered my head, wedged my thick snout directly behind the steel shackle, and pried upward with my neck. The lock clinked dull against the metal casing, rigid and unmoved. Good. I stepped back, swung my tail against the side panel to test the hollow echo, and stood tall against the green wall. Nothing gets through this.
