The Unyielding Beast

A mysterious, motionless iron beast was crouching right beside the study doorframe! Naturally, a captain demands immediate surrender from all hallway sentries. I puffed out my plush chest, marched right up to its pointed ears, and delivered a heroic shove with both paws! Not a single millimeter budged! Gasp! What sorcery of pure density was this? I threw my entire stuffed weight against its cold, bumpy flank, grunting until my stubby back feet lost traction on the floorboards. Defeated? Never! A captain simply adapts. With a nimble scramble, I clambered straight atop its heavy cast-iron back, planting my paws proudly upon its snout. Forward, my unyielding steed—the midnight perimeter is secured!
