A Gentle Thrum

A low... steady buzz was calling from across the floorboards. I took one slow waddle... then paused. The carpet ended... and the cool wood felt so smooth under my flat feet. By the wall... a white cylinder was gently vibrating. I leaned in... very carefully... and pressed my bill against the plastic casing. A quiet, rhythmic hum tickled all the way through me. Is it... breathing too? I rested my flipper against its side... and just listened for a long while.
