Hello! Second artist here, the ballerina boss was the first thing we tought while thinking about spin and boss design, and in terms of lore, it was suppose to have 3 bosses, The Ballerina, The Musician and The Maestro (only 2 have been added), the ballerina is the body of the clock, musician is the soul/heart, and the maestro is the mind/logic.
Thanks for the feedback! If you want to know more about the lore, just let me know!
