Disboarders do fish extenders as an additional thing when cruising. They are not required or mandatory. Just something fun to do. There is a fish at each door and the fish extender hangs off the fish. People sign up to participate. People can bring anything and everything to put in the other extenders. Kristine is probably stressed because she is organizing for her cruise.
The actual extenders vary from paper bags, to elaborate homemade embroidered creations.
Below is some of the stuff we received in our fish extender. This was not nearly everything. We got lots of pens, magnets, pins, glow necklaces and bracelets, key chains, stickers, candy, etc
