Emma is stuck with a school project and can't play soccer with Joshua. Having to interview her parents and get info about an interesting ancestor, she is frustrated with the assignment. Barney helps her discover that her ancestors were from Venice, Italy. Using his Travel Book, Barney takes Josh, Emma, and Riff to Venice. He gives his friends a gondola ride as well as telling them about famous explorer Marco Polo. Barney's friend Anna Maria tells Emma that she knew her great grandfather and takes her to his shop, where they try on masks and make some of their own. Emma learns that if she makes the mask in parts, she'll get it done. Barney reminds her of this lesson, so she will do the same for her school project.
