Create a subrule of ‘Doing the Dance’ called ‘Custom Moves’ with the following text:

All Monkeys have one Custom Move, which they may include in their list of Dance Moves. A Custom Move may contain any one action, but no Custom Move may contain the same action as another. A Monkey may add, remove, or change their Custom Move at any time, except when the Dance is being Done.

Just another excuse for monkey megalomaniacs, isn’t it? No way, have a look at this!
Append the following text to the above subrule:

If the Top Banana believes a Custom Move to be too powerful or complex, or for any other sensible reason (e.g. the move would not work), they may remove it from its owner’s list of Dance Moves at any time. However, they may not remove a Custom Move solely for their own personal gain or the gain of any other Monkey. Any Monkey may contest the removal of a Custom Move by posting a Call for Judgement. If it succeeds, the move may be reinstated. If not, the Top Banana’s decision stands.
