The 'FE' stands for fish extender. You can make or buy it and it hangs outside of your stateroom and it has pockets to place things in. I made one out of pink and green material (girls favorite colors), put their initials on the pockets and some princess iron-on's. They had so much fun looking each day. We signed up for it on the cruise thread and wrote down the cabin #'s for the other families participating; picked up some cute trinkets etc, and then one evening while the girls were in the oceaneears club my Dh and I put the gifts in the other fish extenders for the other families.
