It's Sunday, and Clifford and Emily Elizabeth are going to visit her grandma. But Clifford can't find Mr. Squeaky, his favorite toy mouse！Emily Elizabeth and Clifford return to the places they visited the previous week to look for Mr. Squeaky. On Monday, they went to the playground-no Mr. Squeaky. On Tuesday, they went to the farmer's market-no Mr. Squeaky. Mr. Squeaky isn't at the amusement park they visited on Wednesday, either. Eventually, they find Mr. Squeaky at Grandma's, but not before they look in a pig pen at a farm, and in the water under the dock. Clifford had a busy week！
