A Clue on the Fence

I set out on a grand search across the garden path, keeping my eyes wide open for anyone who looked blocky and red like me! When I reached the base of the wooden garden fence, I spotted something familiar stuck in a splintery crack: two little orange building blocks snapped together! I stretched up on tiptoes and gave the bottom block a friendly tap with both hands. They did not move, but the bright blocks looked just like a Numberblock clue. I stood beside them, tapping my feet to make a little beat so any nearby block friends could hear me calling!
