Nancy regrets trading a piece of jewelry with JoJo and tries to trade back.
Nancy is excited because she will go to the butterfly pavilion at the Natural History Museum. She needs a sketch pad to draw the butterflies but unfortunately, her sketch pad is full. So, she offers to JoJo some stuff she has in exchange for her sketch pad. Jojo only is interested in two butterflies bracelets that seem like a pirate treasure, so they do the trade.
These bracelets didn't fit Nancy, but when she finds out that they can become a necklace, she does everything to trade back. She cannot get it in the right way and ends stealing the necklace. When JoJo notices that the necklace is not in the place where she left it, she goes with her parents to search it, and all goes to ask Nancy if she has seen the necklace.
Nancy tells them what happened, and that she regrets her actions, returning the necklace to JoJo, and apologizing with her. At the finale, JoJo agrees to lend her the necklace, with the condition that she will have to draw her some butterflies at the museum.
