A Worthy Rival

You asked about a dino challenger. I found one! Standing silent against the bookshelf was a dense cast-iron bookend shaped like a horned Triceratops. Heavy. Dark. Daring to share my floor. I let out a soundless roar, planted my claws into the hardwood, and lunged head-first into its iron snout. CLANG! The metallic impact buzzed clean down to my tail tip. The horned beast skidded an inch, scraping the floor with a magnificent screech, but stood firm. Finally—a rival with spine!
