As I was starting up A Darkness in the Marshes (TfW) last night with my group, the players received the Storm Bag from Radagast (it summons a thunderstorm upon opening it, and it is single-use.) However, while I was (in-character) describing the bag as Radagast would, I had him say that he wasn't entirely sure that this was the bag that summoned storms or not (to try to portray him with an absent-minded characteristic).
My players took this to mean something entirely different. They believed due to this that there were two bags lying around; One that summoned storms, and one that did something completely separate. I allowed a player to search the area, and they achieved a great success, so I told them that they were able to also locate a small blue bag and take it with them.
Here's my question: What effect should the blue bag have when opened? I'm open to anything, but something that would work nicely with the scenario in question (either to aid them or hinder them in an appropriate way) would be ideal. Thanks for any help.
