Geo Umizoomi, disguised as a ghost, tries to stifle a giggle beneath the sheet. "OoooOOOoooo! Beware, Little Bill! I am the Spooky Ghost of Umi City!" Little Bill's eyes widen in shock, and he drops his blocks with a clatter.

Little Bill sprints down the path, his voice trembling as he shouts, "Help! There’s a ghost after me! Somebody, help!"

April closes her book and looks up, concern in her eyes. "April! There’s a ghost in the backyard—it chased me all the way here!" "A ghost? Are you sure, Little Bill? Show me where you saw it," she says, standing up and taking his hand.
