Carly Morgan is a supporting character in Mako: Island of Secrets. She works at the Ocean Cafe and is best friends with Evie McLaren. She attempted construction of a romantic relationship with David, who was uninterested due to the sudden arrival of Sirena. This brought her attention to Lyla and Nixie also, (later Ondina and Mimmi as well) who claimed to be Rita's nieces. The girls, who were secretly mermaids, made Carly very suspicious and later she did not hesitate to support Evie's plans to search their house for answers.
