An item that looks and functions like a bag of holding, except in one way.
Players must keep a list of all items in the bag and what order they were put in. If the characters try to pull something out without using the magic word “please,” they roll a dn (where n=the number of items in the bag) and whichever item on the list corresponds to the item rolled is what the player pulls out.
Additionally, if there is only one item in the bag, the players pull out a tree branch that is 1d4 feet long instead.
If the players say “please” when they reach into the bag, they can pull out whatever item they need, no problem.
