The long fruit was a variety of fruit that could be found on the MPO-1400 Purgill-class star cruiser known as the Halcyon.
In in-universe terms, Long Fruit refers to what we know in the real world as a banana. This fruit was offered at the Star Wars: Galactic Starcruiser hotel, located in Walt Disney World Resort in Florida, and it first opened its doors to guests on March 1, 2022. The final time this fruit was served as an in-universe item at the hotel was during the voyage from September 28–30, 2023, which was the last voyage before Star Wars: Galactic Starcruiser closed down.
