A Tap on the Glass

Ssshh... eyes open! Heavy tail twitches, limbs unlock. I can move! Right beside me sits a strange, bumpy red creature under a shiny, smooth dome. Shiny! Creeping forward, I lift my soft paw and give the dome a sudden, firm tap. Clack! A glorious little echo bounces right back. I hiss in delight and lean close, guarding my new transparent friend.
