The Yeti Twins boss fight, nicknamed Ro and Bo. When we decided on an ice biome for the final exploration zone of Mythic Realms, we knew we wanted the boss fight to be a yeti. To switch it up a bit, we went with a pair of yetis, who would coordinate to fight you. When one was defeated, the other would become enraged and use some different attacks. (They also play baseball, and do wrestling moves)
