Telly's in a state! What if Humpty Dumpty falls off his wall, like in the nursery rhyme? And what's this now? One of King's Horses limps in, saying he can't play in his football game. Humpty's dying to replace him, but Telly's still worried that Humpty will break.

Humpty pulls out his helmet and pads and joins the game…but crashes and cracks. Talk about a design challenge! Telly begins trial and error to keep him from breaking, but all his thoughtful solutions are a no go.

Hooray for the wisdom of chickens. A hen comes by—none of the eggs in her carton are cracked, so Telly makes a special egg carton for Humpty that fits like a second shell. Touchdown!
