Larimar is a kind-hearted Gem, who wishes to make others happy. Her misunderstandings of how Earth's society functions lead her to get confused over simple things, such as screams being sounds of joy. She also mentioned to Steven that screams are her favorite sound on Earth, which worried him. Despite this, it is shown that Larimar very much enjoys seeing children laugh, and wishes to make it her purpose on Earth to help them do so by giving out prizes at Beach City Funland.
