A Rolled-Up Surprise

I scrambled out of the sofa crevice and tumbled straight onto the rug, tumbling like a fuzzy snowball! Right across the floor, leaning against the hallway wall, was a rolled-up yoga mat standing upright like a blue hollow tower. Naturally, I couldn't resist. I trotted over and stuck my whole head into the dark round tunnel inside it. When I hummed a little note, the sound bounced back with a fun, buzzing echo that tickled my big ears! I gave it a soft push with my paws, and it tipped over with a gentle whump, unrolling just enough to make a soft ramp for me to sit on.
