I think it would be a good idea to disable the eating of chorus fruit at spawn near the jail to prevent looking at the jail crate early.
I don't think this would need any additional plugin.
I saw GrapeNut the Moderator say that you shouldn't see what is in the prison crate earlier, and I remembered I did just that a few weeks ago. Apparently you are not supposed to know, so you can do this to prevent people from doing what I did.
It will bring more surprise to prison crates and stop people from seeing early.
