Vibrating Beast

A low hum called from across the room! Rhythmic. Deep! I marched straight over and found a tall black metal stalk with a wide round base. Perfect challenger! I lowered my head and pressed my snout firmly against the plastic foot. *BZZZZ!* A glorious buzzing vibration rattled my whole jaw! I planted both feet wide and leaned all my weight in. It didn't budge, just hummed stronger. A mighty standoff!
