Peril on the Rim

A sudden clink reverberated across the timber surface! *Gasp!* Impending tidal wave?! A localized flood catastrophe?! I instantly dropped flat against the wood grain, clutching the edge of a coaster for ballast! But the room stayed dry. I slowly raised my crest and crept forward. Right on the outermost corner of the coffee table sat a heavy ceramic mug—halfway off the rim, teetering precariously! An unchecked slip hazard! If someone brushed past, total containment failure would ensue! Digging my curved hair crest firmly against the cool glazed base, I heaved with my entire round body. *Scrape!* I pushed and nudged until it slid a full three inches inward, locked safely in the center zone. Catastrophe averted!
