Little Yeep plays Big Shot in a metal grate!

I hopped down from the rug to explore that tall white grate by the wall! Gasp! It looked like a row of giant harp strings made of iron. I leaned forward and whacked one metal column with my red mallet—*BONG!* A deep, heavy rumble rolled right through my plush toes! I tapped another rib further along—*PING!* It had a higher chime! Excitedly, I scraped my shaker across the ridged surface—*drrrr-clack!*—sending a rippling echo all the way down the room. I sat back on my round bottom, absolutely thrilled by the giant metallic hum.
