Fortress Inspection

I waddled out through the cracked screen door on my four stubby feet, determined to scout out prime fortress ground before this Jimmy arrives. You mentioned he builds castles, but any proper stronghold has to survive some serious roughhousing first! Down on the concrete porch, I discovered a neat, tidy stack of heavy red landscaping bricks. Prime geometric material. I lined myself up, leaned my square head forward, and launched a full-speed charge straight into the bottom brick. THUNK! The solid brick didn't slide a single millimeter, and I bounced right back onto my rear legs like a rubber ball. That durability passes inspection! Tell Jimmy the cornerstone is officially secured.
