Big fly
Flies are enemies in Rayman Origins. They appear during flying sequences with the Moskito and can be seen for the first time in Hi-Ho Moskito!. They chase the characters from ahead, making undulating movements to avoid their shoots. Compared to smaller enemies, they require more shoots to be killed, but they can be inhaled by the Moskito (or Globox) easily. Flies are some of the few enemies that don't bubblize when killed. There is a robot version of the flies in the Moody Clouds level.
According to the first trailer of the game, flies where supposed to be regular enemies on the game, until the format was changed and they were reduced to flying sequences.
