Greenbottles are green, grinning, flying insects encountered in the PlayStation version of Rayman 2: The Great Escape, where, along with the Denys and the Ludivs, Rayman must free them from the cages in which the Robo-Pirates have imprisoned them. Despite their frog-or fairy-like appearance, the greenbottles are actually flies. They wear a permanent grin on their faces (as seen in most Rayman games except for Rayman 3) and all have a high-pitched voice.
Notably, Murfy, a character who acts as Rayman's coach in several Rayman games and can be controlled in Rayman Legends, is a greenbottle, as revealed in the manual for Rayman 3: Hoodlum Havoc. In all versions of Rayman 2 except for the PlayStation version, Murfy guides Rayman through the game's controls and gives him a few hints. In versions of the game without full voice acting, Murfy whispers to Rayman, but in the PlayStation 2 version, he has a high-pitched voice. In Rayman 3, his personality was further developed and he became an ironic, sarcastic guide for Rayman while traversing the Fairy Council, constantly poking fun at his user manual and breaking the fourth wall.
