The Orange City Gym is headed by Fizzy, also known as the "Floating Orange", who uses Orange-type PokéSweets. She has won 22 battles and lost 56 battles and her gym is full of orange soda, because it goes well with ice cream. There are 2 trainers, and one can be avoided. Once beaten, she gives the player the Soda Badge.
Note: the gym cannot be exited until the leader is defeated. Plan accordingly!
