Sammy sat in the van. He spotted a tin pan on a woven mat.
Pat, pat, pat. A glowing letter P floated into the air. Sammy reached for it.
Rub, rub, rub — M appeared. Knock, knock, knock — V formed. Sammy's eyes grew wide.
Sammy tapped his chest. Nothing. He tapped again. His shoulders dropped.
'Sammy!' called Dad from outside. A letter S floated out of Sammy's mouth.
Sammy opened his mouth again. The S wobbled. Dad said it too, and another S appeared.
Sammy gasped. His dad said it again, and yet another S danced into the light.
Sammy tapped the pan again. Pat, pat, pat. The letter P bounced back.
He tapped his chest. The S rattled softly. The van was full of letters now.
Sammy couldn't stop tapping. Pat, rub, knock. The letters danced and danced.
