A Spiky Discovery

I was checking the tiled territory around the kitchen counter when something bright yellow dropped straight from above! It was a brand-new cleaning sponge shaped with zig-zag grooved edges. When I grabbed the prickly scrubber side, it felt completely rough and armor-plated, just like the osteoderm plates on an Ankylosaurus back! Did you know armored dinosaurs had bony spikes to protect themselves from giant predators? I dragged it across the slick white tiles and propped it firmly beside an upright wooden spoon to build an armored fortress wall for my kitchen base camp!
