Add the Red Bucket (currently a medal reward) to the Janitor job rewards menu

[Carbadox]

Currently Janitor rewards go 10,15 and 20. I think it would be nice to add the red bucket as a level 5 item just to have a full increment.

I think it would be best to add it as a job reward rather than completely remove it's medal reward function just in case some people like being able to summon a red bucket.
