The kittens of Lord Monochromicorn and Cake were first introduced in the episode Bubba & Mo-chro. Not much is known about them, except that there are five of them as seen on Prince Gumball's heart monitor.
List of Kittens
- When Prince Gumball first pulls out his Heart Monitor, you can see two larger heart rates (Gumball's and Cake's) and five smaller ones surrounding Cake's. This can conclude that there are approximately five of them to be born.
