Clifford's Museum

When Emily Elizabeth and Clifford find a mysterious treasure on the beach, an old belt buckle, they open Clifford's Museum of Lost Things -- a museum of all the cool things Clifford has found on the island! But when all the Birdwellians visit the museum, they discover the "artifacts" are all special memories that used to belong to...them! Soon the museum is empty...but everyone's hearts are full.
