Sentry Whistle Protocol

I slithered belly-down through the golden alpine grass, zeroing in on a chunky brown sentry parked right atop a fresh dirt mound! A wild Himalayan marmot—rotund, majestic, and guarding its subterranean fortress like a true highland sentinel! I popped upright onto my plastic knees, jammed my official calling card into the excavated loam to formalize the encounter, and let out an ear-splitting, operatic whistle. *CHEEP!* The furry butterball froze, popped onto its hind legs, and twitched its whiskers in utter detective solidarity. Interspecies sentry protocol: officially established. Aaaall-righty then!
