Mrs. Diller has out the photo album and is showing Cleo old pictures of her as a puppy. Then, she comes to one that isn't of Cleo. But who is this dog? She looks just like Cleo! It turns out that she's Cleo's grandmother, Queenie. She even wore a crown. Mrs. Diller looks around - it turns out she still has that crown and she lets Cleo wear it. Cleo goes off to tell Mac, T-Bone and Clifford all about her crown and her grandmother. T-Bone hears this and is quite impressed. He says that if Cleo's grandmother was a queen, then Cleo must be royalty, in fact, they are now all in the presence of Princess Cleo. Everybody thinks this is pretty neat, but Cleo starts letting it get to her head. Instead of scratching in the grass on her own, she asks Clifford to scratch for her. Then, when they're playing ball, Cleo doesn't take her turn and has T-Bone fetch the ball for her. Finally, when Mac finds a bone and Clifford breaks it into pieces to share, Cleo takes the biggest piece for herself, even though she didn't find it. The next morning, Clifford, T-Bone and Mac are all playing in leaves. "Princess" Cleo is annoyed, how dare they start playing without her? They explain to her- she wouldn't like playing in leaves, after all, it would get her dirty and tired, and a princess should never be dirty and tired. But Cleo likes playing in leaves. She admits that she was a jerk the day before, and decides to drop the whole princess thing. Mac puts on her crown- he thinks it makes a good fit. At Clifford's, Emily Elizabeth reads them all a story about a princess. Cleo says that she'd much rather listen to a story about a princess than be one.
