The marbles inside the jar weren’t in the same order he’d put them in this morning. Boo knew because he remembered every single one. He’d held each one in his paws…searching Wiggle Town, hunting clues. And one marble was out of place. A blue one. Not the normal swirled-blue they’d found in the crawlspace. A different blue. Deeper. Richer. With a faint lightning-shaped streak inside.
