Bloon privacy: Secret bloons
If a bloon has been set to secret, only space members and guests who have been invited can access it or see it. It is completely invisible to other members of the space; it doesn't appear in the list of open bloons.

To make any bloon secret, go into its bloon settings, select the "Privacy" tab, and click on "Secret".
