The Clacking Letters

A shiny red plastic shape on the freezer door caught my eye, stuck right at my nose level! I tapped it with a cautious front paw, and it slid sideways across the smooth metal with a squeak. *Snap!* It suddenly jumped straight toward a blue letter next to it, clamping together with a sharp little clack! My ears shot straight up. I wedged my nose underneath to pry them apart, but whenever I shoved them an inch away, they spun right around and clicked back together like two stubborn puzzle pieces. I spent whole minutes lining up four chunky magnets into a bright, crooked train.
