Emily Johnson proposes an idea to design and sell clothing and costumes for guinea pigs. She was inspired by outfits she saw for guinea pigs in a South Park episode. She plans to design outfits for her own guinea pigs, Roger and Alex, and take photos of them in the costumes to advertise the products. Some potential business names mentioned are Happy Cavies, Happy Guineas, Pigs in Jackets, and Cavy Heaven. The proposed slogan is "Unleash your inner piggy." Emily is looking for feedback on her advert idea.
