- Adored by the Network: A very rare case where a show gets lifted from Nicktoons very quickly in order to premiere on the main network. Since then, Nick has been experimenting with its audience and premiering episodes on different days and times in order to improve its performance. And the best part? The ratings got even better (one episode got in the millions, and did better than its competitor, Unikitty!).
- Dueling Shows: With Unikitty!, which also involves a unicorn-kitten hybrid.
- Screwed by the Network: Originally was this, as after the sneak peek premiere aired on Nickelodeon the show would automatically be passed down to Nicktoons, with new episodes premiering at 9 PM, causing its ratings to plummet hard.
- This happened again when the show was lifted from Nickelodeon from Nicktoons again, giving RBUK the honor of being one of the few shows to be shafted to Nicktoons twice!
- The Wiki Rule: Right here.
