Loosha is a major character in Professor Layton and the Last Specter. Arianna Barde and her brother Tony were very attached to her, and used to play around with her in the lake. She is a minty blue color, and she has blue spots on her belly. Loosha is playful and friendly. She is rather intelligent and loyal, but before she met the Barde siblings, she was rather lonesome as she was the only one of her kind. Loosha was born in Misthallery's Golden Garden. When her parents died, she was the last of her kind left, and suffered from loneliness.
This made her leave the garden for the upper level of the lake, where she found Arianna and Tony. She made friends with them, and kept the siblings company after the death of their father. In the year following up to Last Specter , Descole's machines destroyed various parts of the town in order to find the Golden Garden. Loosha tried to fight them off, which caused the two of them to look like the specter destroying buildings.
To calm Loosha down, Arianna played her ocarina into the town's old irrigation pipes, echoing through the town and calming Loosha. Minutes afterwards, Levin Jakes and his police officers captured Loosha and arrested Arianna, taking them to the town square. After Descole revealed as a true behind for tearing apart of Misthallery.
Loosha once again fought the machine with the help of Layton, Luke, and Emmy. Loosha, realising how to stop the machine, broke down the secondary floodgates of Misthallery's dam, lightly flooding the town and short-circuiting the machine.
Once the battle had ended, Loosha used the last of her strength to break through the primary floodgates of the dam, badly flooding Misthallery, but revealing a hidden passageway to the Golden Garden. Arianna tries to stop Loosha by playing her ocarina, but Loosha didn't listen. Arianna angrily yells at Loosha that she doesn't want to be her friend anymore, before throwing a rock at her.
