Breaching the Wall

The balcony grew cold. I marched back inside! Before me stood a towering wall of heavy, colorful blocks standing upright on a low wooden shelf. No detour! I lowered my snout and charged straight into the row! CRUNCH! Two thick volumes tipped sideways and slid across the polished wood. One fell flat, creating a solid new ramp! I drove my heavy claws onto its spine. It creaked, but held! I raised my head high into the dark gap between shelves. A hidden cavern, carved out by my own force!
