After a dance, any monkies with a dance moves of zero(0) or less shall have their status changed to In The Barrel. If they ended the dance in the barrel, their status does not change, but the following still applies. They then must stay in the barrel until the date changes, but no less than twelve(12) hours. Once they have stayed in the barrel for at least the amount of time stated in the previous sentence, their dance moves shall be set to three(3). Normal rules for exiting the barrel apply.

and as a minor note:
Change the text in the rule Status:

If more than once monkey is to be added back in line, the monkeys are added in alphabetical order.
